Title
tls: fix race between async notify and socket close
Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix race between async notify and socket close
The submitting thread (one which called recvmsg/sendmsg)
may exit as soon as the async crypto handler calls complete()
so any code past that point risks touching already freed data.
Try to avoid the locking and extra flags altogether.
Have the main thread hold an extra reference, this way
we can depend solely on the atomic ref counter for
synchronization.
Don't futz with reiniting the completion, either, we are now
tightly controlling when completion fires.

Per kernel scoring guidance, kTLS bugs triggered by remote peer data are Network.\nAC:L - The attacker controls both sides of the race \u2014 it supplies the data that triggers the async crypto completions and drives the socket teardown (locally via its own close(), remotely by ending the request/connection so the server closes) \u2014 and can retry across thousands of concurrent connections until the window is won.\nPR:N - There is no capability or authorization check anywhere in net/tls; a remote peer of a public kTLS server needs no credentials, and a local attacker needs only an ordinary unprivileged socket to set the TLS ULP and install keys.\nUI:N - No victim action is required; the socket close that closes the race is ordinary application behavior the attacker induces, not a user-performed operation.\nS:U - The corruption is confined to kernel slab memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed `tls_sw_context_rx`/`tls_sw_context_tx` comes from a generic kmalloc cache and can be reclaimed by attacker-controlled objects, so the use-after-free gives control over freed-object contents and can be leveraged for kernel memory disclosure.\nI:H - The callback performs writes into the freed object (`spin_unlock_bh`, `test_and_set_bit` on `tx_bitmask`) and queues a `delayed_work` residing in freed memory whose function pointer is later dereferenced, yielding heap corruption at known offsets and a control-flow hijack primitive.\nA:H - The use-after-free reliably produces slab corruption, oopses and panics, and the lost-wakeup half of the race can leave the submitting thread blocked forever in uninterruptible sleep holding the socket."

Title
net: tls: handle backlogging of crypto requests
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: tls: handle backlogging of crypto requests
Since we're setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on our
requests to the crypto API, crypto_aead_{encrypt,decrypt} can return
-EBUSY instead of -EINPROGRESS in valid situations. For example, when
the cryptd queue for AESNI is full (easy to trigger with an
artificially low cryptd.cryptd_max_cpu_qlen), requests will be enqueued
to the backlog but still processed. In that case, the async callback
will also be called twice: first with err == -EINPROGRESS, which it
seems we can just ignore, then with err == 0.
Compared to Sabrina's original patch this version uses the new
tls_*crypt_async_wait() helpers and converts the EBUSY to
EINPROGRESS to avoid having to modify all the error handling
paths. The handling is identical.

No memory layout or victim state outside the attacker\u0027s influence is required.\nPR:N - A kTLS-offloading server accepts connections from arbitrary unauthenticated clients (no client certificates in the typical deployment), and once the session is established the attacker only needs to send record data. No account or privilege on the target system is required.\nUI:N - The bug triggers automatically during normal kTLS record encryption and decryption on an established connection. No action by any local user or administrator is needed.\nS:U - The use-after-free, double free and page refcount underflow all occur within kernel memory managed by the same security authority. No VM, IOMMU or sandbox boundary is crossed.\nC:H - The freed tls_rec / aead_req+tls_decrypt_ctx blocks are re-read after being reclaimed, yielding an attacker-groomable sock pointer and scatterlist, and the page refcount underflow from the spurious put_page() lets freed pages holding other tenants\u0027 data be re-observed. This is leverageable into arbitrary kernel memory disclosure.\nI:H - The stale callback writes into freed memory (rec-\u003etx_ready, sge-\u003eoffset, ctx-\u003easync_wait.err) and the crypto engine writes attacker-supplied plaintext into pages already released, giving a controlled-content write primitive, compounded by a double kfree() of the decrypt buffer.\nA:H - The use-after-free, double free and page refcount underflow reliably produce slab corruption and kernel panics, and the encrypt_pending/decrypt_pending underflow leaves tls_*crypt_async_wait() waiting on a completion that never arrives, hanging the socket close path."

Title
tls: fix race between tx work scheduling and socket close
Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix race between tx work scheduling and socket close
Similarly to previous commit, the submitting thread (recvmsg/sendmsg)
may exit as soon as the async crypto handler calls complete().
Reorder scheduling the work before calling complete().
This seems more logical in the first place, as it's
the inverse order of what the submitting thread will do.

"value": "AV:N - The flaw is in the net/tls software TX path of a kTLS-terminating server, where the encrypt-then-close sequence is driven entirely by remote client traffic (request eliciting a response plus `Connection: close`/RST), and the remote peer additionally controls whether records stay queued at the head of tx_list via its TCP receive window, which is the precondition for reaching the post-complete() code. No local access to the target is needed.\nAC:L - The attacker controls both sides of the race \u2014 one side issues the sendmsg that leaves an async encryption in flight, the other issues the close that blocks in tls_encrypt_async_wait() and then frees ctx \u2014 and can retry across thousands of concurrent connections at no cost. No memory layout or victim state outside the attacker\u0027s influence is required.\nPR:N - A kTLS-offloading HTTPS server accepts connections from arbitrary unauthenticated clients with no client certificate in the typical deployment; locally, setsockopt(TCP_ULP,\"tls\") plus TLS_TX requires no capability at all once the tls module is loaded. Neither path needs an account or privilege on the target.\nUI:N - The race fires during ordinary kTLS record encryption and socket teardown on an established connection. No action by any local user or administrator is required.\nS:U - The use-after-free on struct tls_sw_context_tx and the resulting timer/workqueue corruption all occur in kernel memory managed by the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - After kfree(ctx) the callback and the later timer expiry re-read freed, attacker-groomable memory \u2014 timer-\u003efunction, dwork-\u003ewq, and tx_work-\u003esk, the last of which is dereferenced as a struct sock * by tx_work_handler/tls_tx_records. Controlling that fake sock and the redirected call is leverageable into arbitrary kernel memory disclosure.\nI:H - The stale callback performs an atomic bit-set into the reallocated slab object at a fixed offset and writes dwork-\u003ewq, dwork-\u003ecpu and timer-\u003eexpires into freed memory, then links that freed object into the global timer wheel. That yields a controlled heap write plus a function pointer read from reclaimed memory, i.e. a control-flow hijack primitive.\nA:H - Arming a delayed_work inside a freed slab object after cancel_delayed_work_sync() reliably produces slab and timer-wheel corruption, and tx_work_handler running against an already-freed TLS context oopses on the stale sk. Any of these panics the kernel."

Title
drm/amdgpu: fix use-after-free bug
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix use-after-free bug
The bug can be triggered by sending a single amdgpu_gem_userptr_ioctl
to the AMDGPU DRM driver on any ASICs with an invalid address and size.
The bug was reported by Joonkyo Jung <joonkyoj@yonsei.ac.kr>.
For example the following code:
static void Syzkaller1(int fd)
{
struct drm_amdgpu_gem_userptr arg;
int ret;
arg.addr = 0xffffffffffff0000;
arg.size = 0x80000000; /*2 Gb*/
arg.flags = 0x7;
ret = drmIoctl(fd, 0xc1186451/*amdgpu_gem_userptr_ioctl*/, &arg);
}
Due to the address and size are not valid there is a failure in
amdgpu_hmm_register->mmu_interval_notifier_insert->__mmu_interval_notifier_insert->
check_shl_overflow, but we even the amdgpu_hmm_register failure we still call
amdgpu_hmm_unregister into amdgpu_gem_object_free which causes access to a bad address.
The following stack is below when the issue is reproduced when Kazan is enabled:

Title
mm/swap: fix race when skipping swapcache
Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/swap: fix race when skipping swapcache
When skipping swapcache for SWP_SYNCHRONOUS_IO, if two or more threads
swapin the same entry at the same time, they get different pages (A, B).
Before one thread (T0) finishes the swapin and installs page (A) to the
PTE, another thread (T1) could finish swapin of page (B), swap_free the
entry, then swap out the possibly modified page reusing the same entry.
It breaks the pte_same check in (T0) because PTE value is unchanged,
causing ABA problem. Thread (T0) will install a stalled page (A) into the
PTE and cause data corruption.
One possible callstack is like this:
CPU0 CPU1
---- ----
do_swap_page() do_swap_page() with same entry
<direct swapin path> <direct swapin path>
<alloc page A> <alloc page B>
swap_read_folio() <- read to page A swap_read_folio() <- read to page B
<slow on later locks or interrupt> <finished swapin first>
... set_pte_at()
swap_free() <- entry is free
<write to page B, now page A stalled>
<swap out page B to same swap entry>
pte_same() <- Check pass, PTE seems
unchanged, but page A
is stalled!
swap_free() <- page B content lost!
set_pte_at() <- staled page A installed!
And besides, for ZRAM, swap_free() allows the swap device to discard the
entry content, so even if page (B) is not modified, if swap_read_folio()
on CPU0 happens later than swap_free() on CPU1, it may also cause data
loss.
To fix this, reuse swapcache_prepare which will pin the swap entry using
the cache flag, and allow only one thread to swap it in, also prevent any
parallel code from putting the entry in the cache. Release the pin after
PT unlocked.
Racers just loop and wait since it's a rare and very short event. A
schedule_timeout_uninterruptible(1) call is added to avoid repeated page
faults wasting too much CPU, causing livelock or adding too much noise to
perf statistics. A similar livelock issue was described in commit
029c4628b2eb ("mm: swap: get rid of livelock in swapin readahead")
Reproducer:
This race issue can be triggered easily using a well constructed
reproducer and patched brd (with a delay in read path) [1]:
With latest 6.8 mainline, race caused data loss can be observed easily:
$ gcc -g -lpthread test-thread-swap-race.c && ./a.out
Polulating 32MB of memory region...
Keep swapping out...
Starting round 0...
Spawning 65536 workers...
32746 workers spawned, wait for done...
Round 0: Error on 0x5aa00, expected 32746, got 32743, 3 data loss!
Round 0: Error on 0x395200, expected 32746, got 32743, 3 data loss!
Round 0: Error on 0x3fd000, expected 32746, got 32737, 9 data loss!
Round 0 Failed, 15 data loss!
This reproducer spawns multiple threads sharing the same memory region
using a small swap device. Every two threads updates mapped pages one by
one in opposite direction trying to create a race, with one dedicated
thread keep swapping out the data out using madvise.
The reproducer created a reproduce rate of about once every 5 minutes, so
the race should be totally possible in production.
After this patch, I ran the reproducer for over a few hundred rounds and
no data loss observed.
Performance overhead is minimal, microbenchmark swapin 10G from 32G

Bluetooth: Avoid potential use-after-free in hci_error_reset
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Avoid potential use-after-free in hci_error_reset
While handling the HCI_EV_HARDWARE_ERROR event, if the underlying
BT controller is not responding, the GPIO reset mechanism would
free the hci_dev and lead to a use-after-free in hci_error_reset.

"value": "AV:A - The `HCI_EV_HARDWARE_ERROR` event that queues `hci_error_reset` is emitted by the Bluetooth controller, and an attacker within Bluetooth radio range can induce a controller firmware exception (the well-documented BrakTooth-class malformed-LMP faults) to generate it while simultaneously leaving the controller unresponsive, which is the exact precondition for the reset/unregister race. This is radio-proximity access, not routable network access.\nAC:L - Once the controller is wedged, the sequence is effectively deterministic: `btintel_hw_error()` blocks for two full `HCI_INIT_TIMEOUT` intervals while `hci_cmd_timeout()` counts to five and fires the GPIO reset, so the race window in which `hci_error_reset` runs against `hci_unregister_dev`/`hci_release_dev` is seconds wide and both sides are driven by the same attacker-induced controller failure. The bug was reproducible enough to be observed in the field on shipping ChromeOS/Intel AX201 hardware.\nPR:N - An over-the-air attacker needs no pairing, bonding, authentication, or any account on the target \u2014 malformed link-layer traffic that faults the controller firmware is processed before any credential check. No host-side privileges are involved at all since the triggering event arrives from the controller.\nUI:N - No victim action is required; the hardware error event, the command timeouts, the GPIO reset and the resulting USB disconnect/unregister all occur automatically inside the kernel once the controller faults.\nS:U - The use-after-free corrupts kernel heap memory within the same security authority as the vulnerable code; no VM, hypervisor, or IOMMU boundary is crossed.\nC:H - `hci_release_dev()` frees `hdev-\u003eworkqueue` (and ultimately `kfree(hdev)`) while `hci_error_reset` is still executing, so `queue_work_on()` reads `wq-\u003eflags` and `wq-\u003ecpu_pwq` out of a freed slab object the attacker can groom by reclaiming it, yielding a kernel-memory read primitive and disclosure of adjacent heap contents and pointers.\nI:H - After the freed `workqueue_struct` is reclaimed with attacker-controlled data, `queue_work_on()` performs a list insertion into the pool worklist derived from that freed memory, giving a controlled write primitive suitable for corrupting adjacent kernel objects and hijacking control flow; the stale `hdev` is likewise written through by the continuing close/open sequence.\nA:H - The confirmed use-after-free reliably oopses or panics the kernel (the reported crash in `queue_work_on` from `hci_error_reset`), and the freed/destroyed workqueue also strands the subsequent `destroy_workqueue(hdev-\u003ereq_workqueue)` drain, permanently wedging the Bluetooth stack."

...
The splat occurs because skb->data points past skb->head allocated area.
This is because neigh layer does:
__skb_pull(skb, skb_network_offset(skb));
... but skb_network_offset() returns a negative offset and __skb_pull()
arg is unsigned. IOW, we skb->data gets "adjusted" by a huge value.
The negative value is returned because skb->head and skb->data distance is
more than 64k and skb->network_header (u16) has wrapped around.
The bug is in the ip_tunnel infrastructure, which can cause
dev->needed_headroom to increment ad infinitum.
The syzkaller reproducer consists of packets getting routed via a gre
tunnel, and route of gre encapsulated packets pointing at another (ipip)
tunnel. The ipip encapsulation finds gre0 as next output device.
This results in the following pattern:
1). First packet is to be sent out via gre0.
Route lookup found an output device, ipip0.
2).
ip_tunnel_xmit for gre0 bumps gre0->needed_headroom based on the future
output device, rt.dev->needed_headroom (ipip0).
3).
ip output / start_xmit moves skb on to ipip0. which runs the same
code path again (xmit recursion).
4).
Routing step for the post-gre0-encap packet finds gre0 as output device
to use for ipip0 encapsulated packet.
tunl0->needed_headroom is then incremented based on the (already bumped)
gre0 device headroom.
This repeats for every future packet:
gre0->needed_headroom gets inflated because previous packets' ipip0 step
incremented rt->dev (gre0) headroom, and ipip0 incremented because gre0
needed_headroom was increased.
For each subsequent packet, gre/ipip0->needed_headroom grows until
post-expand-head reallocations result in a skb->head/data distance of
more than 64k.
Once that happens, skb->network_header (u16) wraps around when
pskb_expand_head tries to make sure that skb_network_offset() is unchanged
after the headroom expansion/reallocation.
After this skb_network_offset(skb) returns a different (and negative)
result post headroom expansion.
The next trip to neigh layer (or anything else that would __skb_pull the
network header) makes skb->data point to a memory location outside
skb->head area.
v2: Cap the needed_headroom update to an arbitarily chosen upperlimit to
prevent perpetual increase instead of dropping the headroom increment
completely.

IOW, we skb-\u003edata gets \"adjusted\" by a huge value.\n\nThe negative value is returned because skb-\u003ehead and skb-\u003edata distance is\nmore than 64k and skb-\u003enetwork_header (u16) has wrapped around.\n\nThe bug is in the ip_tunnel infrastructure, which can cause\ndev-\u003eneeded_headroom to increment ad infinitum.\n\nThe syzkaller reproducer consists of packets getting routed via a gre\ntunnel, and route of gre encapsulated packets pointing at another (ipip)\ntunnel. The ipip encapsulation finds gre0 as next output device.\n\nThis results in the following pattern:\n\n1). First packet is to be sent out via gre0.\nRoute lookup found an output device, ipip0.\n\n2).\nip_tunnel_xmit for gre0 bumps gre0-\u003eneeded_headroom based on the future\noutput device, rt.dev-\u003eneeded_headroom (ipip0).\n\n3).\nip output / start_xmit moves skb on to ipip0. which runs the same\ncode path again (xmit recursion).\n\n4).\nRouting step for the post-gre0-encap packet finds gre0 as output device\nto use for ipip0 encapsulated packet.\n\ntunl0-\u003eneeded_headroom is then incremented based on the (already bumped)\ngre0 device headroom.\n\nThis repeats for every future packet:\n\ngre0-\u003eneeded_headroom gets inflated because previous packets\u0027 ipip0 step\nincremented rt-\u003edev (gre0) headroom, and ipip0 incremented because gre0\nneeded_headroom was increased.\n\nFor each subsequent packet, gre/ipip0-\u003eneeded_headroom grows until\npost-expand-head reallocations result in a skb-\u003ehead/data distance of\nmore than 64k.\n\nOnce that happens, skb-\u003enetwork_header (u16) wraps around when\npskb_expand_head tries to make sure that skb_network_offset() is unchanged\nafter the headroom expansion/reallocation.\n\nAfter this skb_network_offset(skb) returns a different (and negative)\nresult post headroom expansion.\n\nThe next trip to neigh layer (or anything else that would __skb_pull the\nnetwork header) makes skb-\u003edata point to a memory location outside\nskb-\u003ehead area.\n\nv2: Cap the needed_headroom update to an arbitarily chosen upperlimit to\nprevent perpetual increase instead of dropping the headroom increment\ncompletely."

"value": "AV:L - The attacker must locally configure a two-device ip_tunnel routing cycle (gre0 \u2194 tunl0) via rtnetlink/ioctl and then transmit packets through a local socket; a remote peer cannot create the tunnel topology that drives the headroom growth.\nAC:L - The headroom inflation is fully deterministic \u2014 each transmitted packet monotonically increases dev-\u003eneeded_headroom until the u16 network_header wraps, with no race and no dependence on memory layout the attacker cannot influence. The required ipip/gre modules are standard on virtually all distributions.\nPR:L - An unprivileged user gains CAP_NET_ADMIN over a private netns via unshare -Urn, since rtnetlink checks netlink_net_capable() against the netns owning user_ns, and tunl0/gre0 fallback devices are auto-created in every netns because sysctl_fb_tunnels_only_for_init_net defaults to 0.\nUI:N - The attacker performs the entire setup and packet transmission alone; no victim action or interaction is required.\nS:U - The corruption occurs in kernel memory within the same security authority; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - After the offset overflow skb-\u003edata points ~4GB away in the kernel direct map, producing the syzbot-confirmed KASAN out-of-bounds/use-after-free read in __skb_flow_dissect, and the resulting packet\u0027s payload is read from that arbitrary kernel memory and transmitted to the attacker-chosen tunnel destination \u2014 up to ~64KB of kernel memory disclosure.\nI:H - skb_push() only validates data \u003c head, so iptunnel_xmit() writes a 20-byte IP header (with attacker-controlled saddr/daddr/tos/ttl) plus the GRE header and attacker-chosen GRE key into out-of-bounds kernel memory, giving a partially controlled write primitive suitable for corrupting adjacent kernel objects.\nA:H - The confirmed use-after-free/out-of-bounds access reliably causes a KASAN report, oops, or panic (unmapped-address dereference or skb_under_panic), and the unbounded needed_headroom growth also forces ever-larger skb reallocations."
