Title
vxlan: vnifilter: Fix unlocked deletion of default FDB entry
Summary
In the Linux kernel, the following vulnerability has been resolved:
vxlan: vnifilter: Fix unlocked deletion of default FDB entry
When a VNI is deleted from a VXLAN device in 'vnifilter' mode, the FDB
entry associated with the default remote (assuming one was configured)
is deleted without holding the hash lock. This is wrong and will result
in a warning [1] being generated by the lockdep annotation that was
added by commit ebe642067455 ("vxlan: Create wrappers for FDB lookup").
Reproducer:
# ip link add vx0 up type vxlan dstport 4789 external vnifilter local 192.0.2.1
# bridge vni add vni 10010 remote 198.51.100.1 dev vx0
# bridge vni del vni 10010 dev vx0
Fix by acquiring the hash lock before the deletion and releasing it
afterwards. Blame the original commit that introduced the issue rather
than the one that exposed it.

==================================================================
It has been reported that trace_seq_to_buffer() tries to copy more data
than PAGE_SIZE to buf. Therefore, to prevent this, we should use the
smaller of trace_seq_used(&iter->seq) and PAGE_SIZE as an argument.

There is no network-facing path to `tracing_splice_read_pipe()`.\nAC:L - The overflow is deterministic and fully attacker-driven: generate more than one page of formatted trace output (a single ~4096-byte `trace_marker` record, or simply let `tracing_fill_pipe_page()` accumulate events up to the 8K trace_seq limit) and then splice from trace_pipe. No race, no memory-layout luck, and no non-default kernel config is needed.\nPR:L - `tracing_open_pipe()` contains no capability check whatsoever \u2014 reachability is gated only by DAC on the tracefs inode, and tracefs exposes `uid=`/`gid=`/`mode=` mount parameters precisely so a non-root group can be granted ftrace access. Android grants `shell`/atrace/Perfetto (`AID_READTRACEFS`) access to trace_pipe and distro/CI/observability deployments commonly chgrp the tracing tree, so an unprivileged local account reaches this path.\nUI:N - The attacker performs every step (open, generate trace data, splice) from its own process. No victim action or interaction is required.\nS:U - The out-of-bounds write and disclosure occur within kernel memory under the same security authority as the kernel itself; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Before the fix `spd.partial[i].len` was set to `trace_seq_used()` (up to ~8152) for a 4096-byte page, so `splice_to_pipe()` returns a pipe buffer that lets userspace read roughly 4KB of adjacent kernel memory directly \u2014 an arbitrary-content kernel infoleak, on top of the OOB write\u0027s exploitability for further disclosure.\nI:H - `trace_seq_to_buffer()` memcpy\u0027s up to ~4056 bytes past the end of a freshly allocated order-0 page into adjacent kernel memory, with largely attacker-chosen content (e.g. arbitrary bytes injected via `trace_marker`). A ~4KB controlled linear-map overflow with attacker-groomable neighbours is a strong write primitive suitable for control-flow hijacking.\nA:H - The overflow corrupts whatever kernel memory follows the page, reliably producing KASAN splats, oopses, or panics as reported by syzbot, and it can be re-triggered at will."

Title
ksmbd: fix use-after-free in kerberos authentication
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix use-after-free in kerberos authentication
Setting sess->user = NULL was introduced to fix the dangling pointer
created by ksmbd_free_user. However, it is possible another thread could
be operating on the session and make use of sess->user after it has been
passed to ksmbd_free_user but before sess->user is set to NULL.

Title
iommu/amd: Fix potential buffer overflow in parse_ivrs_acpihid
Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/amd: Fix potential buffer overflow in parse_ivrs_acpihid
There is a string parsing logic error which can lead to an overflow of hid
or uid buffers. Comparing ACPIID_LEN against a total string length doesn't
take into account the lengths of individual hid and uid buffers so the
check is insufficient in some cases. For example if the length of hid
string is 4 and the length of the uid string is 260, the length of str
will be equal to ACPIID_LEN + 1 but uid string will overflow uid buffer
which size is 256.
The same applies to the hid string with length 13 and uid string with
length 250.
Check the length of hid and uid strings separately to prevent
buffer overflow.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

arm64: errata: Add missing sentinels to Spectre-BHB MIDR arrays
Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: errata: Add missing sentinels to Spectre-BHB MIDR arrays
Commit a5951389e58d ("arm64: errata: Add newer ARM cores to the
spectre_bhb_loop_affected() lists") added some additional CPUs to the
Spectre-BHB workaround, including some new arrays for designs that
require new 'k' values for the workaround to be effective.
Unfortunately, the new arrays omitted the sentinel entry and so
is_midr_in_range_list() will walk off the end when it doesn't find a
match. With UBSAN enabled, this leads to a crash during boot when
is_midr_in_range_list() is inlined (which was more common prior to
c8c2647e69be ("arm64: Make _midr_in_range_list() an exported
function")):

Title
drm/nouveau: Fix WARN_ON in nouveau_fence_context_kill()
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: Fix WARN_ON in nouveau_fence_context_kill()
Nouveau is mostly designed in a way that it's expected that fences only
ever get signaled through nouveau_fence_signal(). However, in at least
one other place, nouveau_fence_done(), can signal fences, too. If that
happens (race) a signaled fence remains in the pending list for a while,
until it gets removed by nouveau_fence_update().
Should nouveau_fence_context_kill() run in the meantime, this would be
a bug because the function would attempt to set an error code on an
already signaled fence.
Have nouveau_fence_context_kill() check for a fence being signaled.
Severity

Title
sch_htb: make htb_qlen_notify() idempotent
Summary
In the Linux kernel, the following vulnerability has been resolved:
sch_htb: make htb_qlen_notify() idempotent
htb_qlen_notify() always deactivates the HTB class and in fact could
trigger a warning if it is already deactivated. Therefore, it is not
idempotent and not friendly to its callers, like fq_codel_dequeue().
Let's make it idempotent to ease qdisc_tree_reduce_backlog() callers'
life.
Severity
No CVSS data available.

Title
perf/x86/intel: KVM: Mask PEBS_ENABLE loaded for guest with vCPU's value.
Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/intel: KVM: Mask PEBS_ENABLE loaded for guest with vCPU's value.
When generating the MSR_IA32_PEBS_ENABLE value that will be loaded on
VM-Entry to a KVM guest, mask the value with the vCPU's desired PEBS_ENABLE
value. Consulting only the host kernel's host vs. guest masks results in
running the guest with PEBS enabled even when the guest doesn't want to use
PEBS. Because KVM uses perf events to proxy the guest virtual PMU, simply
looking at exclude_host can't differentiate between events created by host
userspace, and events created by KVM on behalf of the guest.
Running the guest with PEBS unexpectedly enabled typically manifests as
crashes due to a near-infinite stream of #PFs. E.g. if the guest hasn't
written MSR_IA32_DS_AREA, the CPU will hit page faults on address '0' when
trying to record PEBS events.
The issue is most easily reproduced by running `perf kvm top` from before
commit 7b100989b4f6 ("perf evlist: Remove __evlist__add_default") (after
which, `perf kvm top` effectively stopped using PEBS). The userspace side
of perf creates a guest-only PEBS event, which intel_guest_get_msrs()
misconstrues a guest-*owned* PEBS event.
Arguably, this is a userspace bug, as enabling PEBS on guest-only events
simply cannot work, and userspace can kill VMs in many other ways (there
is no danger to the host). However, even if this is considered to be bad
userspace behavior, there's zero downside to perf/KVM restricting PEBS to
guest-owned events.
Note, commit 854250329c02 ("KVM: x86/pmu: Disable guest PEBS temporarily
in two rare situations") fixed the case where host userspace is profiling
KVM *and* userspace, but missed the case where userspace is profiling only
KVM.

Consulting only the host kernel\u0027s host vs. guest masks results in\nrunning the guest with PEBS enabled even when the guest doesn\u0027t want to use\nPEBS. Because KVM uses perf events to proxy the guest virtual PMU, simply\nlooking at exclude_host can\u0027t differentiate between events created by host\nuserspace, and events created by KVM on behalf of the guest.\n\nRunning the guest with PEBS unexpectedly enabled typically manifests as\ncrashes due to a near-infinite stream of #PFs. E.g. if the guest hasn\u0027t\nwritten MSR_IA32_DS_AREA, the CPU will hit page faults on address \u00270\u0027 when\ntrying to record PEBS events.\n\nThe issue is most easily reproduced by running `perf kvm top` from before\ncommit 7b100989b4f6 (\"perf evlist: Remove __evlist__add_default\") (after\nwhich, `perf kvm top` effectively stopped using PEBS).\tThe userspace side\nof perf creates a guest-only PEBS event, which intel_guest_get_msrs()\nmisconstrues a guest-*owned* PEBS event.\n\nArguably, this is a userspace bug, as enabling PEBS on guest-only events\nsimply cannot work, and userspace can kill VMs in many other ways (there\nis no danger to the host). However, even if this is considered to be bad\nuserspace behavior, there\u0027s zero downside to perf/KVM restricting PEBS to\nguest-owned events.\n\nNote, commit 854250329c02 (\"KVM: x86/pmu: Disable guest PEBS temporarily\nin two rare situations\") fixed the case where host userspace is profiling\nKVM *and* userspace, but missed the case where userspace is profiling only\nKVM."

Title
ksmbd: prevent out-of-bounds stream writes by validating *pos
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: prevent out-of-bounds stream writes by validating *pos
ksmbd_vfs_stream_write() did not validate whether the write offset
(*pos) was within the bounds of the existing stream data length (v_len).
If *pos was greater than or equal to v_len, this could lead to an
out-of-bounds memory write.
This patch adds a check to ensure *pos is less than v_len before
proceeding. If the condition fails, -EINVAL is returned.
