Reproduction script:
mkdir -p /mnt/nfsshare
mkdir -p /mnt/nfs/netns_1
mkfs.ext4 /dev/sdb
mount /dev/sdb /mnt/nfsshare
systemctl restart nfs-server
chmod 777 /mnt/nfsshare
exportfs -i -o rw,no_root_squash *:/mnt/nfsshare
ip netns add netns_1
ip link add name veth_1_peer type veth peer veth_1
ifconfig veth_1_peer 11.11.0.254 up
ip link set veth_1 netns netns_1
ip netns exec netns_1 ifconfig veth_1 11.11.0.1
ip netns exec netns_1 /root/iptables -A OUTPUT -d 11.11.0.254 -p tcp \
--tcp-flags FIN FIN -j DROP
(note: In my environment, a DESTROY_CLIENTID operation is always sent
immediately, breaking the nfs tcp connection.)
ip netns exec netns_1 timeout -s 9 300 mount -t nfs -o proto=tcp,vers=4.1 \
11.11.0.254:/mnt/nfsshare /mnt/nfs/netns_1
ip netns del netns_1
The reason here is that the tcp socket in netns_1 (nfs side) has been
shutdown and closed (done in xs_destroy), but the FIN message (with ack)
is discarded, and the nfsd side keeps sending retransmission messages.
As a result, when the tcp sock in netns_1 processes the received message,
it sends the message (FIN message) in the sending queue, and the tcp timer
is re-established. When the network namespace is deleted, the net structure
accessed by tcp's timer handler function causes problems.
To fix this problem, let's hold netns refcnt for the tcp kernel socket as
done in other modules. This is an ugly hack which can easily be backported
to earlier kernels. A proper fix which cleans up the interfaces will
follow, but may not be so easy to backport.

When the network namespace is deleted, the net structure\naccessed by tcp\u0027s timer handler function causes problems.\n\nTo fix this problem, let\u0027s hold netns refcnt for the tcp kernel socket as\ndone in other modules. This is an ugly hack which can easily be backported\nto earlier kernels. A proper fix which cleans up the interfaces will\nfollow, but may not be so easy to backport."

A remote peer only controls the enabling condition (withholding the FIN ACK so the retransmit timer stays armed); it cannot initiate the namespace teardown that constitutes the free.\nAC:L - The upstream reproducer is a deterministic script: the attacker controls both sides \u2014 keeping the TCP retransmit timer armed (drop the FIN, or use a peer that never ACKs) and the timing of the netns deletion. No condition depends on chance or on state the attacker cannot influence.\nPR:L - The freeing half of the UAF is driven by the ordinary, unprivileged unshare(CLONE_NEWNET) syscall path shown in the KASAN allocation trace, and in containerized deployments the namespace-confined \"root\" that creates the netns, mounts NFS, and tears the netns down is an unprivileged principal on the host. Choosing the higher severity where privilege attribution is ambiguous, this is Low rather than High.\nUI:N - The entire sequence \u2014 namespace creation, RPC transport setup, blocking the FIN, and namespace deletion \u2014 is performed by the attacker\u0027s own processes. No action by a separate victim user is needed.\nS:U - The use-after-free corrupts kernel memory and is exploited within the kernel\u0027s own security authority; there is no crossing into a different security scope such as a hypervisor or IOMMU boundary.\nC:H - tcp_retransmit_timer() reads sysctl fields and the net-\u003emib percpu pointer out of the freed struct net; with the net_namespace slab object reclaimed by attacker-groomed allocations this becomes a controlled read primitive, and per guidance any use-after-free is scored High.\nI:H - __NET_INC_STATS() dereferences and increments through a percpu pointer loaded from the freed struct net, giving a write through an attacker-influenceable stale pointer; a use-after-free of a groomable slab object is exploitable for heap manipulation and control-flow hijacking.\nA:H - The confirmed observable effect is a KASAN slab-use-after-free in tcp_write_timer_handler() executing in softirq/IRQ context on the idle CPU, which readily oopses or panics the machine."

Title
nfsd: make sure exp active before svc_export_show
Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: make sure exp active before svc_export_show
The function `e_show` was called with protection from RCU. This only
ensures that `exp` will not be freed. Therefore, the reference count for
`exp` can drop to zero, which will trigger a refcount use-after-free
warning when `exp_get` is called. To resolve this issue, use
`cache_get_rcu` to ensure that `exp` remains active.
------------[ cut here ]------------
refcount_t: addition on 0; use-after-free.

"value": "AV:L - The vulnerable `e_show()` path is only entered via `read()` on local pseudo-files (`/proc/fs/nfs/exports`, `/proc/fs/nfsd/exports`, `/proc/fs/nfsd/export_stats`); no remote NFS request reaches this seq_file code.\nAC:L - The attacker fully controls the triggering side and can loop reads across many threads indefinitely, while the freeing side (sunrpc `cache_clean` expiry of export/negative entries) runs continuously on any active NFS server and can be further churned by unauthenticated RPC traffic to local nfsd, so the race is repeatable at will.\nPR:L - `/proc/fs/nfs/exports` defaults to 0444 (`proc_create` mode 0 \u2192 `S_IRUGO`) and `/proc/fs/nfsd/{exports,export_stats}` are registered `S_IRUGO` under a 0755 directory, so any unprivileged local user can read them \u2014 no capability, namespace trick, or root required.\nUI:N - The attacker performs the read itself; no action by any other user or administrator is needed.\nS:U - The refcount underflow and subsequent use-after-free are confined to the kernel\u0027s own memory and the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `svc_export_show()` reads already-freed memory (`ex_stats` was `kfree()`d non-RCU, `ex_client` auth_domain released, `ex_path` dentry/mnt put) and formats it into the seq buffer returned to the unprivileged reader, and the freed percpu counter pointer yields a wild read \u2014 a direct kernel heap information disclosure that reclaimed-slab grooming makes attacker-influenceable.\nI:H - On the affected 4.20+ trees without zero-checking `refcount_t`, the bogus 0\u21921 increment is followed by a matching put that re-runs `svc_export_put()`, producing double `kfree()` of `ex_stats`/`ex_uuid`, double `path_put()`/`auth_domain_put()` and a double `kfree_rcu()` \u2014 a double-free/refcount-underflow primitive on kmalloc objects that is a well-established route to arbitrary write and privilege escalation.\nA:H - The `refcount_t: addition on 0` WARNING is an oops splat (immediate panic with `panic_on_warn`), and dereferencing the freed `ex_stats` percpu pointer plus the double-free of dentry/mount/auth_domain references reliably crash the kernel \u2014 an unprivileged user can trigger this repeatedly."

Title
net: inet: do not leave a dangling sk pointer in inet_create()
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: inet: do not leave a dangling sk pointer in inet_create()
sock_init_data() attaches the allocated sk object to the provided sock
object. If inet_create() fails later, the sk object is freed, but the
sock object retains the dangling pointer, which may create use-after-free
later.
Clear the sk pointer in the sock object on error.

Title
Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2cap_sock_create()
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2cap_sock_create()
bt_sock_alloc() allocates the sk object and attaches it to the provided
sock object. On error l2cap_sock_alloc() frees the sk object, but the
dangling pointer is still attached to the sock object, which may create
use-after-free in other code.

Title
proc: fix UAF in proc_get_inode()
Summary
In the Linux kernel, the following vulnerability has been resolved:
proc: fix UAF in proc_get_inode()
Fix race between rmmod and /proc/XXX's inode instantiation.
The bug is that pde->proc_ops don't belong to /proc, it belongs to a
module, therefore dereferencing it after /proc entry has been registered
is a bug unless use_pde/unuse_pde() pair has been used.
use_pde/unuse_pde can be avoided (2 atomic ops!) because pde->proc_ops
never changes so information necessary for inode instantiation can be
saved _before_ proc_register() in PDE itself and used later, avoiding
pde->proc_ops->... dereference.

free_module(mod);

No network protocol handling is involved.\nAC:L - The attacker fully controls their side of the race and can hold the window open continuously \u2014 `/proc/net` entries use `proc_net_dentry_ops` whose `.d_revalidate` always returns 0, so every single access re-runs `proc_lookup_de()`/`proc_get_inode()`, and fresh procfs mounts or netns via `unshare -Ur` defeat any dcache caching. On the realistic deployment targets (Android, embedded, automotive) module load/unload cycles are frequent and user-inducible via device/radio state changes, so no condition requires attacker-unattainable luck.\nPR:L - Triggering the vulnerable dereference requires only the ability to look up a path under /proc, which is mode 0555 and open to any unprivileged local user; no capability is checked anywhere on the lookup path. Unprivileged users can additionally use user namespaces to obtain fresh procfs/netns instances and to autoload modules that register `/proc/net` entries.\nUI:N - The attacker\u0027s exploitation loop is entirely self-driven \u2014 a continuous stat() loop on the target /proc entry \u2014 and requires no victim to open a file, mount a filesystem, or otherwise participate.\nS:U - The use-after-free occurs in kernel memory and its consequences are confined to the kernel\u0027s own security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - This is a use-after-free on freed module memory; once the vmalloc/execmem region is reclaimed and re-populated (e.g. by a subsequent module load), the stale read feeds attacker-influenceable data into inode setup, and UAF primitives of this class are leveraged for kernel memory disclosure.\nI:H - The UAF causes the kernel to select `i_fop` based on freed, potentially reallocated memory, yielding a stale-object/type-confusion condition on the instantiated inode; use-after-free on kernel structures is exploitable via heap grooming for control-flow-relevant corruption.\nA:H - The commit documents an unrecoverable oops \u2014 \"BUG: unable to handle page fault for address: fffffbfff80a702b \u2026 Oops: 0000 [#1] PREEMPT SMP KASAN PTI\" at `proc_get_inode+0x302` \u2014 and the attacker can retrigger it at will with a stat() loop, causing kernel crash/denial of service."

Title
netfilter: nft_tunnel: fix geneve_opt type confusion addition
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_tunnel: fix geneve_opt type confusion addition
When handling multiple NFTA_TUNNEL_KEY_OPTS_GENEVE attributes, the
parsing logic should place every geneve_opt structure one by one
compactly. Hence, when deciding the next geneve_opt position, the
pointer addition should be in units of char *.
However, the current implementation erroneously does type conversion
before the addition, which will lead to heap out-of-bounds write.

Table creation, object creation, and module autoload all succeed inside that namespace.\nUI:N - The attacker performs the entire sequence themselves via socket syscalls; no action by any other user or administrator is needed.\nS:U - The corruption stays within the kernel\u0027s own memory and security authority, yielding standard local privilege escalation rather than crossing a virtualization or IOMMU boundary.\nC:H - The mirrored bug in nft_tunnel_opts_dump() performs an out-of-bounds read whose offset and length both come from adjacent heap memory, and nla_put() copies that data into the netlink reply delivered to userspace, disclosing arbitrary kernel heap contents. The OOB write additionally enables full memory disclosure via corrupted neighbouring objects.\nI:H - This is an out-of-bounds heap write with an attacker-controlled destination (up to ~1000 bytes past the start of a ~400-byte kmalloc-512 object) and up to 124 bytes of fully attacker-controlled content, allowing corruption of sprayed adjacent slab objects and control-flow hijacking for privilege escalation.\nA:H - The KASAN report in the fix commit shows a 124-byte slab-out-of-bounds write; corrupting neighbouring slab objects reliably produces kernel oops/panic, and the trigger can be repeated at will from an unprivileged namespace."

According to the debug log, the same req received two SYN-ACK in a very
short time, very likely because the client retransmits the syn ack due
to multiple reasons.
Even if the packets are transmitted with a relevant time interval, they
can be processed by the server on different CPUs concurrently). The
'subflow_req->msk' ownership is transferred to the subflow the first,
and there will be a risk of a null pointer dereference here.
This patch fixes this issue by moving the 'subflow_req->msk' under the
`own_req == true` conditional.
Note that the !msk check in subflow_hmac_valid() can be dropped, because
the same check already exists under the own_req mpj branch where the
code has been moved to.
