Title
ip6_tunnel: clear skb2->cb[] in ip4ip6_err()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ip6_tunnel: clear skb2->cb[] in ip4ip6_err()
Oskar Kjos reported the following problem.
ip4ip6_err() calls icmp_send() on a cloned skb whose cb[] was written
by the IPv6 receive path as struct inet6_skb_parm. icmp_send() passes
IPCB(skb2) to __ip_options_echo(), which interprets that cb[] region
as struct inet_skb_parm (IPv4). The layouts differ: inet6_skb_parm.nhoff
at offset 14 overlaps inet_skb_parm.opt.rr, producing a non-zero rr
value. __ip_options_echo() then reads optlen from attacker-controlled
packet data at sptr[rr+1] and copies that many bytes into dopt->__data,
a fixed 40-byte stack buffer (IP_OPTIONS_DATA_FIXED_SIZE).
To fix this we clear skb2->cb[], as suggested by Oskar Kjos.
Also add minimal IPv4 header validation (version == 4, ihl >= 5).

Title
ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()
Sashiko AI-review observed:
In ip6_err_gen_icmpv6_unreach(), the skb is an outer IPv4 ICMP error packet
where its cb contains an IPv4 inet_skb_parm. When skb is cloned into skb2
and passed to icmp6_send(), it uses IP6CB(skb2).
IP6CB interprets the IPv4 inet_skb_parm as an inet6_skb_parm. The cipso
offset in inet_skb_parm.opt directly overlaps with dsthao in inet6_skb_parm
at offset 18.
If an attacker sends a forged ICMPv4 error with a CIPSO IP option, dsthao
would be a non-zero offset. Inside icmp6_send(), mip6_addr_swap() is called
and uses ipv6_find_tlv(skb, opt->dsthao, IPV6_TLV_HAO).
This would scan the inner, attacker-controlled IPv6 packet starting at that
offset, potentially returning a fake TLV without checking if the remaining
packet length can hold the full 18-byte struct ipv6_destopt_hao.
Could mip6_addr_swap() then perform a 16-byte swap that extends past the end
of the packet data into skb_shared_info?
Should the cb array also be cleared in ip6_err_gen_icmpv6_unreach() and
ip6ip6_err() to prevent this?
This patch implements the first suggestion.
I am not sure if ip6ip6_err() needs to be changed.
A separate patch would be better anyway.

When skb is cloned into skb2\n and passed to icmp6_send(), it uses IP6CB(skb2).\n\n IP6CB interprets the IPv4 inet_skb_parm as an inet6_skb_parm. The cipso\n offset in inet_skb_parm.opt directly overlaps with dsthao in inet6_skb_parm\n at offset 18.\n\n If an attacker sends a forged ICMPv4 error with a CIPSO IP option, dsthao\n would be a non-zero offset. Inside icmp6_send(), mip6_addr_swap() is called\n and uses ipv6_find_tlv(skb, opt-\u003edsthao, IPV6_TLV_HAO).\n\n This would scan the inner, attacker-controlled IPv6 packet starting at that\n offset, potentially returning a fake TLV without checking if the remaining\n packet length can hold the full 18-byte struct ipv6_destopt_hao.\n\n Could mip6_addr_swap() then perform a 16-byte swap that extends past the end\n of the packet data into skb_shared_info?\n\n Should the cb array also be cleared in ip6_err_gen_icmpv6_unreach() and\n ip6ip6_err() to prevent this?\n\nThis patch implements the first suggestion.\n\nI am not sure if ip6ip6_err() needs to be changed.\nA separate patch would be better anyway."

As a network-reachable memory corruption primitive, this is defensibly high confidentiality impact.\nI:H - The same swap writes 16 attacker-controlled bytes from the IPv6 source address beyond packet data into skb_shared_info or adjacent skb metadata.

Title
wifi: brcmfmac: validate bsscfg indices in IF events
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: validate bsscfg indices in IF events
brcmf_fweh_handle_if_event() validates the firmware-provided interface
index before it touches drvr->iflist[], but it still uses the raw
bsscfgidx field as an array index without a matching range check.
Reject IF events whose bsscfg index does not fit in drvr->iflist[]
before indexing the interface array.
[add missing wifi prefix]

Title
netfilter: ctnetlink: ensure safe access to master conntrack
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: ctnetlink: ensure safe access to master conntrack
Holding reference on the expectation is not sufficient, the master
conntrack object can just go away, making exp->master invalid.
To access exp->master safely:
- Grab the nf_conntrack_expect_lock, this gets serialized with
clean_from_lists() which also holds this lock when the master
conntrack goes away.
- Hold reference on master conntrack via nf_conntrack_find_get().
Not so easy since the master tuple to look up for the master conntrack
is not available in the existing problematic paths.
This patch goes for extending the nf_conntrack_expect_lock section
to address this issue for simplicity, in the cases that are described
below this is just slightly extending the lock section.
The add expectation command already holds a reference to the master
conntrack from ctnetlink_create_expect().
However, the delete expectation command needs to grab the spinlock
before looking up for the expectation. Expand the existing spinlock
section to address this to cover the expectation lookup. Note that,
the nf_ct_expect_iterate_net() calls already grabs the spinlock while
iterating over the expectation table, which is correct.
The get expectation command needs to grab the spinlock to ensure master
conntrack does not go away. This also expands the existing spinlock
section to cover the expectation lookup too. I needed to move the
netlink skb allocation out of the spinlock to keep it GFP_KERNEL.
For the expectation events, the IPEXP_DESTROY event is already delivered
under the spinlock, just move the delivery of IPEXP_NEW under the
spinlock too because the master conntrack event cache is reached through
exp->master.
While at it, add lockdep notations to help identify what codepaths need
to grab the spinlock.

Title
xfs: fix freemap adjustments when adding xattrs to leaf blocks
Summary
In the Linux kernel, the following vulnerability has been resolved:
xfs: fix freemap adjustments when adding xattrs to leaf blocks
xfs/592 and xfs/794 both trip this assertion in the leaf block freemap
adjustment code after ~20 minutes of running on my test VMs:
ASSERT(ichdr->firstused >= ichdr->count * sizeof(xfs_attr_leaf_entry_t)
+ xfs_attr3_leaf_hdr_size(leaf));
Upon enabling quite a lot more debugging code, I narrowed this down to
fsstress trying to set a local extended attribute with namelen=3 and
valuelen=71. This results in an entry size of 80 bytes.
At the start of xfs_attr3_leaf_add_work, the freemap looks like this:
i 0 base 448 size 0 rhs 448 count 46
i 1 base 388 size 132 rhs 448 count 46
i 2 base 2120 size 4 rhs 448 count 46
firstused = 520
where "rhs" is the first byte past the end of the leaf entry array.
This is inconsistent -- the entries array ends at byte 448, but
freemap[1] says there's free space starting at byte 388!
By the end of the function, the freemap is in worse shape:
i 0 base 456 size 0 rhs 456 count 47
i 1 base 388 size 52 rhs 456 count 47
i 2 base 2120 size 4 rhs 456 count 47
firstused = 440
Important note: 388 is not aligned with the entries array element size
of 8 bytes.
Based on the incorrect freemap, the name area starts at byte 440, which
is below the end of the entries array! That's why the assertion
triggers and the filesystem shuts down.
How did we end up here? First, recall from the previous patch that the
freemap array in an xattr leaf block is not intended to be a
comprehensive map of all free space in the leaf block. In other words,
it's perfectly legal to have a leaf block with:
* 376 bytes in use by the entries array
* freemap[0] has [base = 376, size = 8]
* freemap[1] has [base = 388, size = 1500]
* the space between 376 and 388 is free, but the freemap stopped
tracking that some time ago
If we add one xattr, the entries array grows to 384 bytes, and
freemap[0] becomes [base = 384, size = 0]. So far, so good. But if we
add a second xattr, the entries array grows to 392 bytes, and freemap[0]
gets pushed up to [base = 392, size = 0]. This is bad, because
freemap[1] hasn't been updated, and now the entries array and the free
space claim the same space.
The fix here is to adjust all freemap entries so that none of them
collide with the entries array. Note that this fix relies on commit
2a2b5932db6758 ("xfs: fix attr leaf header freemap.size underflow") and
the previous patch that resets zero length freemap entries to have
base = 0.

The attacker can invoke the xattr operation directly.\nS:U - The vulnerability corrupts XFS/kernel filesystem metadata within the same kernel security authority. It does not cross a VM, IOMMU, or sandbox boundary.\nC:H - The bug causes attacker-controlled corruption of xattr leaf entries in a kernel metadata buffer, and those entries drive later xattr parsing offsets and namespace interpretation. Under the required uncertainty rule, this memory/metadata corruption is treated as potentially leveragable for high confidentiality impact.\nI:H - The faulty freemap lets xattr name/value data be allocated on top of the leaf entry array, corrupting XFS metadata and potentially access-control/security xattr state. This is attacker-controlled metadata corruption with documented data-loss potential, so integrity impact is High.\nA:H - The known failure mode trips XFS corruption assertions/verifiers and shuts down the filesystem.

Title
md/bitmap: fix GPF in write_page caused by resize race
Summary
In the Linux kernel, the following vulnerability has been resolved:
md/bitmap: fix GPF in write_page caused by resize race
A General Protection Fault occurs in write_page() during array resize:
RIP: 0010:write_page+0x22b/0x3c0 [md_mod]
This is a use-after-free race between bitmap_daemon_work() and
__bitmap_resize(). The daemon iterates over `bitmap->storage.filemap`
without locking, while the resize path frees that storage via
md_bitmap_file_unmap(). `quiesce()` does not stop the md thread,
allowing concurrent access to freed pages.
Fix by holding `mddev->bitmap_info.mutex` during the bitmap update.
Severity
No CVSS data available.

Title
netfilter: xt_tcpmss: check remaining length before reading optlen
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: xt_tcpmss: check remaining length before reading optlen
Quoting reporter:
In net/netfilter/xt_tcpmss.c (lines 53-68), the TCP option parser reads
op[i+1] directly without validating the remaining option length.
If the last byte of the option field is not EOL/NOP (0/1), the code attempts
to index op[i+1]. In the case where i + 1 == optlen, this causes an
out-of-bounds read, accessing memory past the optlen boundary
(either reading beyond the stack buffer _opt or the
following payload).
Severity
8.2 (High)

The attacker controls the packet contents and no race or external timing condition is required.\nPR:N - The packet sender does not need credentials or local privileges to reach the rule once it is present on a firewall/router/host. Installing rules requires CAP_NET_ADMIN, including via network namespaces, but that is not required for the remote-trigger scenario.\nUI:N - No victim user action is required; packet processing occurs automatically in the kernel receive/forward/output netfilter path.\nS:U - The impact remains within the kernel/network stack security authority on the affected system. There is no VM escape, IOMMU/DMA boundary crossing, or other scope-changing boundary involved.\nC:L - The bug is a bounded one-byte out-of-bounds read beyond the TCP options buffer, potentially into adjacent stack or skb data. Because it is only a single byte and is not a broad arbitrary read primitive, confidentiality impact is Low rather than High.\nI:N - The vulnerable operation only reads op[i+1] and uses it to advance the parser; it does not write to kernel memory or packet data. I found no control-flow or data-integrity primitive from this one-byte read.\nA:H - Malformed packets can repeatedly trigger the out-of-bounds read in softirq/netfilter packet processing. On instrumented or hardened kernels this can produce a KASAN/oops/panic, so availability impact is High under highest-defensible scoring."

Title
mm/page_alloc: clear page->private in free_pages_prepare()
Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/page_alloc: clear page->private in free_pages_prepare()
Several subsystems (slub, shmem, ttm, etc.) use page->private but don't
clear it before freeing pages. When these pages are later allocated as
high-order pages and split via split_page(), tail pages retain stale
page->private values.
This causes a use-after-free in the swap subsystem. The swap code uses
page->private to track swap count continuations, assuming freshly
allocated pages have page->private == 0. When stale values are present,
swap_count_continued() incorrectly assumes the continuation list is valid
and iterates over uninitialized page->lru containing LIST_POISON values,
causing a crash:
KASAN: maybe wild-memory-access in range [0xdead000000000100-0xdead000000000107]
RIP: 0010:__do_sys_swapoff+0x1151/0x1860
Fix this by clearing page->private in free_pages_prepare(), ensuring all
freed pages have clean state regardless of previous use.

Title
netfilter: flowtable: strictly check for maximum number of actions
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: flowtable: strictly check for maximum number of actions
The maximum number of flowtable hardware offload actions in IPv6 is:
* ethernet mangling (4 payload actions, 2 for each ethernet address)
* SNAT (4 payload actions)
* DNAT (4 payload actions)
* Double VLAN (4 vlan actions, 2 for popping vlan, and 2 for pushing)
for QinQ.
* Redirect (1 action)
Which makes 17, while the maximum is 16. But act_ct supports for tunnels
actions too. Note that payload action operates at 32-bit word level, so
mangling an IPv6 address takes 4 payload actions.
Update flow_action_entry_next() calls to check for the maximum number of
supported actions.
While at it, rise the maximum number of actions per flow from 16 to 24
so this works fine with IPv6 setups.

The required action combination is complex but attacker-controlled in the local netlink setup.\nPR:L - nfnetlink/rtnetlink require CAP_NET_ADMIN, but this is reachable as a low-privileged local user in a user and network namespace where CAP_NET_ADMIN is granted. It does not require real init-namespace root in the highest defensible local scenario.\nUI:N - No victim user action is required after the attacker configures the local netfilter/tc objects. The attacker can generate the traffic needed to instantiate the flow.\nS:U - The corruption occurs inside the kernel networking/offload subsystem and impacts the same kernel security authority. This is standard kernel memory corruption, not a cross-scope escape such as guest-to-host.\nC:H - The bug is a slab out-of-bounds write past a flex-array of flow_action_entry objects. Kernel heap memory corruption is defensibly exploitable for information disclosure primitives.\nI:H - The unchecked append writes attacker-influenced flow_action_entry fields beyond the allocated action array. Such kernel heap out-of-bounds writes are defensibly exploitable for arbitrary memory corruption or code execution.\nA:H - Even without full exploitation, writing past the allocated flow action array can corrupt adjacent kernel heap objects and cause an oops or panic. Repeated triggering can therefore cause high availability impact."

Title
Bluetooth: hci_event: fix potential UAF in SSP passkey handlers
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_event: fix potential UAF in SSP passkey handlers
hci_conn lookup and field access must be covered by hdev lock in
hci_user_passkey_notify_evt() and hci_keypress_notify_evt(), otherwise
the connection can be freed concurrently.
Extend the hci_dev_lock critical section to cover all conn usage in both
handlers.
Keep the existing keypress notification behavior unchanged by routing
the early exits through a common unlock path.
