CVE-2025-68801 (GCVE-0-2025-68801)

Title
mlxsw: spectrum_router: Fix neighbour use-after-free
Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_router: Fix neighbour use-after-free
We sometimes observe use-after-free when dereferencing a neighbour [1].
The problem seems to be that the driver stores a pointer to the
neighbour, but without holding a reference on it. A reference is only
taken when the neighbour is used by a nexthop.
Fix by simplifying the reference counting scheme. Always take a
reference when storing a neighbour pointer in a neighbour entry. Avoid
taking a referencing when the neighbour is used by a nexthop as the
neighbour entry associated with the nexthop already holds a reference.
Tested by running the test that uncovered the problem over 300 times.
Without this patch the problem was reproduced after a handful of
iterations.

Title
ksmbd: fix buffer validation by including null terminator size in EA length
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix buffer validation by including null terminator size in EA length
The smb2_set_ea function, which handles Extended Attributes (EA),
was performing buffer validation checks that incorrectly omitted the size
of the null terminating character (+1 byte) for EA Name.
This patch fixes the issue by explicitly adding '+ 1' to EaNameLength where
the null terminator is expected to be present in the buffer, ensuring
the validation accurately reflects the total required buffer size.
Severity
No CVSS data available.

Title
media: vidtv: initialize local pointers upon transfer of memory ownership
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: vidtv: initialize local pointers upon transfer of memory ownership
vidtv_channel_si_init() creates a temporary list (program, service, event)
and ownership of the memory itself is transferred to the PAT/SDT/EIT
tables through vidtv_psi_pat_program_assign(),
vidtv_psi_sdt_service_assign(), vidtv_psi_eit_event_assign().
The problem here is that the local pointer where the memory ownership
transfer was completed is not initialized to NULL. This causes the
vidtv_psi_pmt_create_sec_for_each_pat_entry() function to fail, and
in the flow that jumps to free_eit, the memory that was freed by
vidtv_psi_*_table_destroy() can be accessed again by
vidtv_psi_*_event_destroy() due to the uninitialized local pointer, so it
is freed once again.
Therefore, to prevent use-after-free and double-free vulnerability,
local pointers must be initialized to NULL when transferring memory
ownership.
Severity
No CVSS data available.

Title
ksmbd: vfs: fix race on m_flags in vfs_cache
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: vfs: fix race on m_flags in vfs_cache
ksmbd maintains delete-on-close and pending-delete state in
ksmbd_inode->m_flags. In vfs_cache.c this field is accessed under
inconsistent locking: some paths read and modify m_flags under
ci->m_lock while others do so without taking the lock at all.
Examples:
- ksmbd_query_inode_status() and __ksmbd_inode_close() use
ci->m_lock when checking or updating m_flags.
- ksmbd_inode_pending_delete(), ksmbd_set_inode_pending_delete(),
ksmbd_clear_inode_pending_delete() and ksmbd_fd_set_delete_on_close()
used to read and modify m_flags without ci->m_lock.
This creates a potential data race on m_flags when multiple threads
open, close and delete the same file concurrently. In the worst case
delete-on-close and pending-delete bits can be lost or observed in an
inconsistent state, leading to confusing delete semantics (files that
stay on disk after delete-on-close, or files that disappear while still
in use).
Fix it by:
- Making ksmbd_query_inode_status() look at m_flags under ci->m_lock
after dropping inode_hash_lock.
- Adding ci->m_lock protection to all helpers that read or modify
m_flags (ksmbd_inode_pending_delete(), ksmbd_set_inode_pending_delete(),
ksmbd_clear_inode_pending_delete(), ksmbd_fd_set_delete_on_close()).
- Keeping the existing ci->m_lock protection in __ksmbd_inode_close(),
and moving the actual unlink/xattr removal outside the lock.
This unifies the locking around m_flags and removes the data race while
preserving the existing delete-on-close behaviour.

Title
KVM: Disallow toggling KVM_MEM_GUEST_MEMFD on an existing memslot
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: Disallow toggling KVM_MEM_GUEST_MEMFD on an existing memslot
Reject attempts to disable KVM_MEM_GUEST_MEMFD on a memslot that was
initially created with a guest_memfd binding, as KVM doesn't support
toggling KVM_MEM_GUEST_MEMFD on existing memslots. KVM prevents enabling
KVM_MEM_GUEST_MEMFD, but doesn't prevent clearing the flag.
Failure to reject the new memslot results in a use-after-free due to KVM
not unbinding from the guest_memfd instance. Unbinding on a FLAGS_ONLY
change is easy enough, and can/will be done as a hardening measure (in
anticipation of KVM supporting dirty logging on guest_memfd at some point),
but fixing the use-after-free would only address the immediate symptom.

svcrdma: use rc_pageoff for memcpy byte offset
Summary
In the Linux kernel, the following vulnerability has been resolved:
svcrdma: use rc_pageoff for memcpy byte offset
svc_rdma_copy_inline_range added rc_curpage (page index) to the page
base instead of the byte offset rc_pageoff. Use rc_pageoff so copies
land within the current page.

Title
ipvs: fix ipv4 null-ptr-deref in route error path
Summary
In the Linux kernel, the following vulnerability has been resolved:
ipvs: fix ipv4 null-ptr-deref in route error path
The IPv4 code path in __ip_vs_get_out_rt() calls dst_link_failure()
without ensuring skb->dev is set, leading to a NULL pointer dereference
in fib_compute_spec_dst() when ipv4_link_failure() attempts to send
ICMP destination unreachable messages.
The issue emerged after commit ed0de45a1008 ("ipv4: recompile ip options
in ipv4_link_failure") started calling __ip_options_compile() from
ipv4_link_failure(). This code path eventually calls fib_compute_spec_dst()
which dereferences skb->dev. An attempt was made to fix the NULL skb->dev
dereference in commit 0113d9c9d1cc ("ipv4: fix null-deref in
ipv4_link_failure"), but it only addressed the immediate dev_net(skb->dev)
dereference by using a fallback device. The fix was incomplete because
fib_compute_spec_dst() later in the call chain still accesses skb->dev
directly, which remains NULL when IPVS calls dst_link_failure().
The crash occurs when:
1. IPVS processes a packet in NAT mode with a misconfigured destination
2. Route lookup fails in __ip_vs_get_out_rt() before establishing a route
3. The error path calls dst_link_failure(skb) with skb->dev == NULL
4. ipv4_link_failure() → ipv4_send_dest_unreach() →
__ip_options_compile() → fib_compute_spec_dst()
5. fib_compute_spec_dst() dereferences NULL skb->dev
Apply the same fix used for IPv6 in commit 326bf17ea5d4 ("ipvs: fix
ipv6 route unreach panic"): set skb->dev from skb_dst(skb)->dev before
calling dst_link_failure().

The fix was incomplete because\nfib_compute_spec_dst() later in the call chain still accesses skb-\u003edev\ndirectly, which remains NULL when IPVS calls dst_link_failure().\n\nThe crash occurs when:\n1. IPVS processes a packet in NAT mode with a misconfigured destination\n2. Route lookup fails in __ip_vs_get_out_rt() before establishing a route\n3. The error path calls dst_link_failure(skb) with skb-\u003edev == NULL\n4. ipv4_link_failure() \u2192 ipv4_send_dest_unreach() \u2192\n __ip_options_compile() \u2192 fib_compute_spec_dst()\n5. fib_compute_spec_dst() dereferences NULL skb-\u003edev\n\nApply the same fix used for IPv6 in commit 326bf17ea5d4 (\"ipvs: fix\nipv6 route unreach panic\"): set skb-\u003edev from skb_dst(skb)-\u003edev before\ncalling dst_link_failure().\n\nKASAN: null-ptr-deref in range [0x0000000000000328-0x000000000000032f]\nCPU: 1 PID: 12732 Comm: syz.1.3469 Not tainted 6.6.114 #2\nRIP: 0010:__in_dev_get_rcu include/linux/inetdevice.h:233\nRIP: 0010:fib_compute_spec_dst+0x17a/0x9f0 net/ipv4/fib_frontend.c:285\nCall Trace:\n \u003cTASK\u003e\n spec_dst_fill net/ipv4/ip_options.c:232\n spec_dst_fill net/ipv4/ip_options.c:229\n __ip_options_compile+0x13a1/0x17d0 net/ipv4/ip_options.c:330\n ipv4_send_dest_unreach net/ipv4/route.c:1252\n ipv4_link_failure+0x702/0xb80 net/ipv4/route.c:1265\n dst_link_failure include/net/dst.h:437\n __ip_vs_get_out_rt+0x15fd/0x19e0 net/netfilter/ipvs/ip_vs_xmit.c:412\n ip_vs_nat_xmit+0x1d8/0xc80 net/netfilter/ipvs/ip_vs_xmit.c:764"

Title
io_uring: fix filename leak in __io_openat_prep()
Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring: fix filename leak in __io_openat_prep()
__io_openat_prep() allocates a struct filename using getname(). However,
for the condition of the file being installed in the fixed file table as
well as having O_CLOEXEC flag set, the function returns early. At that
point, the request doesn't have REQ_F_NEED_CLEANUP flag set. Due to this,
the memory for the newly allocated struct filename is not cleaned up,
causing a memory leak.
Fix this by setting the REQ_F_NEED_CLEANUP for the request just after the
successful getname() call, so that when the request is torn down, the
filename will be cleaned up, along with other resources needing cleanup.
Severity
No CVSS data available.

Title
net/sched: ets: Remove drr class from the active list if it changes to strict
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: ets: Remove drr class from the active list if it changes to strict
Whenever a user issues an ets qdisc change command, transforming a
drr class into a strict one, the ets code isn't checking whether that
class was in the active list and removing it. This means that, if a
user changes a strict class (which was in the active list) back to a drr
one, that class will be added twice to the active list [1].
Doing so with the following commands:
tc qdisc add dev lo root handle 1: ets bands 2 strict 1
tc qdisc add dev lo parent 1:2 handle 20: \
tbf rate 8bit burst 100b latency 1s
tc filter add dev lo parent 1: basic classid 1:2
ping -c1 -W0.01 -s 56 127.0.0.1
tc qdisc change dev lo root handle 1: ets bands 2 strict 2
tc qdisc change dev lo root handle 1: ets bands 2 strict 1
ping -c1 -W0.01 -s 56 127.0.0.1
Will trigger the following splat with list debug turned on:
