Title
misc: fastrpc: Fix NULL pointer dereference in rpmsg callback
Summary
In the Linux kernel, the following vulnerability has been resolved:
misc: fastrpc: Fix NULL pointer dereference in rpmsg callback
A NULL pointer dereference was observed on Hawi at boot when the DSP
sends a glink message before fastrpc_rpmsg_probe() has completed
initialization:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000178
pc : _raw_spin_lock_irqsave+0x34/0x8c
lr : fastrpc_rpmsg_callback+0x3c/0xcc [fastrpc]
...
Call trace:
_raw_spin_lock_irqsave+0x34/0x8c (P)
fastrpc_rpmsg_callback+0x3c/0xcc [fastrpc]
qcom_glink_native_rx+0x538/0x6a4
qcom_glink_smem_intr+0x14/0x24 [qcom_glink_smem]
The faulting address 0x178 corresponds to the lock variable inside
struct fastrpc_channel_ctx, confirming that cctx is NULL when
fastrpc_rpmsg_callback() attempts to take the spinlock.
There are two issues here. First, dev_set_drvdata() is called before
spin_lock_init() and idr_init(), leaving a window where the callback
can retrieve a valid cctx pointer but operate on an uninitialized
spinlock. Second, the rpmsg channel becomes live as soon as the driver
is bound, so fastrpc_rpmsg_callback() can fire before dev_set_drvdata()
is called at all, resulting in dev_get_drvdata() returning NULL.
Fix both issues by moving all cctx initialization ahead of
dev_set_drvdata() so the structure is fully initialized before it
becomes visible to the callback, and add a NULL check in
fastrpc_rpmsg_callback() as a guard against any remaining window.
Severity
No CVSS data available.

Title
locking/rtmutex: Skip remove_waiter() when waiter is not enqueued
Summary
In the Linux kernel, the following vulnerability has been resolved:
locking/rtmutex: Skip remove_waiter() when waiter is not enqueued
syzbot triggered the following splat in remove_waiter() via
FUTEX_CMP_REQUEUE_PI:
KASAN: null-ptr-deref in range [0x0000000000000a88-0x0000000000000a8f]
class_raw_spinlock_constructor
remove_waiter+0x159/0x1200 kernel/locking/rtmutex.c:1561
rt_mutex_start_proxy_lock+0x103/0x120
futex_requeue+0x10e4/0x20d0
__x64_sys_futex+0x34f/0x4d0
task_blocks_on_rt_mutex() does not arm the waiter upon deadlock detection,
leaving waiter->task nil, where 3bfdc63936dd ("rtmutex: Use waiter::task instead
of current in remove_waiter()") made this fatal.
Furthermore, rt_mutex_start_proxy_lock() should not be calling into remove_waiter()
upon a successfully grabbing the rtmutex. 1a1fb985f2e2 ("futex: Handle early deadlock
return correctly"), moved the remove_waiter() out of __rt_mutex_start_proxy_lock()
(where 'ret' was only ever 0 or < 0) into the wrapper. Tighten this check to
account for try_to_take_rt_mutex().
Severity
No CVSS data available.

Title
fuse: limit FUSE_NOTIFY_RETRIEVE to uptodate folios
Summary
In the Linux kernel, the following vulnerability has been resolved:
fuse: limit FUSE_NOTIFY_RETRIEVE to uptodate folios
FUSE_NOTIFY_RETRIEVE must be limited to uptodate folios; !uptodate folios
can contain uninitialized data.
Since FUSE_NOTIFY_RETRIEVE is intended to only return data that is already
in the page cache and not wait for data from the FUSE daemon, treat
!uptodate folios as if they weren't present.
This only has security impact on systems that don't enable automatic
zero-initialization of all page allocations via
CONFIG_INIT_ON_ALLOC_DEFAULT_ON or init_on_alloc=1.
Severity
No CVSS data available.

Title
agp/amd64: Fix broken error propagation in agp_amd64_probe()
Summary
In the Linux kernel, the following vulnerability has been resolved:
agp/amd64: Fix broken error propagation in agp_amd64_probe()
A NULL pointer dereference was observed in the AMD64 AGP driver when
running in a virtualized environment (e.g. qemu/kvm) without a physical
AMD northbridge. The crash occurs in amd64_fetch_size() when attempting
to dereference the pointer returned by node_to_amd_nb(0).
The root cause of this crash is broken error propagation in
agp_amd64_probe(): When no AMD northbridges are found, cache_nbs()
correctly returns -ENODEV. However, the probe function erroneously
checks the return value against exactly -1, rather than < 0.
As a result, the hardware absence error is masked, allowing the driver
to improperly proceed with initialization. It eventually calls
agp_add_bridge(), which invokes amd64_fetch_size(). Since the hardware
does not exist, node_to_amd_nb(0) returns NULL, leading to a General
Protection Fault (GPF) when accessing its ->misc member.
Fix the issue by correcting the error check in agp_amd64_probe() to
abort properly when cache_nbs() returns any negative error code. This
prevents the driver from erroneously proceeding without hardware, thereby
avoiding the subsequent NULL pointer dereference at its source.
Severity

Title
debugobjects: Do not fill_pool() if pi_blocked_on
Summary
In the Linux kernel, the following vulnerability has been resolved:
debugobjects: Do not fill_pool() if pi_blocked_on
On RT enabled kernels, fill_pool() ends up calling rtlock_lock(), which
asserts if current::pi_blocked_on is set, because a task can obviously only
block on one lock as otherwise the priority inheritenace chain gets
corrupted.
Prevent this by expanding the conditional to take current::pi_blocked_on

Title
KVM: x86: Fix shadow paging use-after-free due to unexpected role
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Fix shadow paging use-after-free due to unexpected role
Commit 0cb2af2ea66ad ("KVM: x86: Fix shadow paging use-after-free due
to unexpected GFN") fixed a shadow paging mismatch between stored and
computed GFNs; the bug could be triggered by changing a PDE mapping from
outside the guest, and then deleting a memslot. The rmap_remove()
call would miss entries created after the PDE change because the GFN
of the leaf SPTE does not match the GFN of the struct kvm_mmu_page.
A similar hole however remains if the modified PDE points to a non-leaf
page. In this case the gfn can be made to match, but the role does not
match: the original large 2MB page creates a kvm_mmu_page with direct=1,
while the new 4KB needs a kvm_mmu_page with direct=0. However,
kvm_mmu_get_child_sp() does not compare the role, and therefore reuses
the page.
The next step is installing a leaf (4KB) SPTE on the new path which
records an rmap entry under the gfn resolved by the walk. But when
that child is zapped its parent kvm_mmu_page has direct=1 and
kvm_mmu_page_get_gfn() computes the gfn for the 4KB page as
sp->gfn + index instead of using sp->shadowed_translation[] (or sp->gfns[]
in older kernels). It therefore fails to remove the recorded entry.
When the memslot is dropped the shadow page is freed but the rmap
entry survives, as in the scenario that was already fixed. Code that
later walks that gfn (dirty logging, MMU notifier invalidation, and
so on) dereferences an sptep that lies in the freed page, causing the
use-after-free.

The trigger is caused by guest execution and KVM memory-management operations.\nS:C - This is a KVM guest-to-host escape class vulnerability, crossing from the guest security authority into the host kernel/hypervisor. Compromise can affect resources outside the guest\u2019s own scope.\nC:H - The stale rmap entry dereferences an SPTE pointer in freed shadow-page memory, creating a kernel use-after-free. Such memory corruption can be leveraged for host kernel information disclosure and arbitrary memory access.\nI:H - The use-after-free can corrupt host kernel shadow-MMU/rmap state and provides a plausible path to host kernel code execution or arbitrary modification. Public analysis treats this as a KVM escape class issue, so high integrity impact is defensible.\nA:H - At minimum, walking the stale rmap can dereference freed memory and crash or panic the host kernel. A malicious guest can repeatedly trigger the condition, causing high availability impact to the host and colocated guests."

Title
ipv6: account for fraggap on the paged allocation path
Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: account for fraggap on the paged allocation path
In __ip6_append_data(), when the paged-allocation branch is taken
(MSG_MORE / NETIF_F_SG / large fraglen), alloclen and pagedlen are
computed as
alloclen = fragheaderlen + transhdrlen;
pagedlen = datalen - transhdrlen;
datalen already includes fraggap (datalen = length + fraggap). When
fraggap is non-zero, this is not the first skb and transhdrlen is zero.
The fraggap bytes carried over from the previous skb are copied just past
the fragment headers in the new skb's linear area. The linear area is
therefore undersized by fraggap bytes while pagedlen is overstated by the
same amount, and the copy writes past skb->end into the trailing
skb_shared_info.
An unprivileged user can trigger this via a UDPv6 socket using
MSG_MORE together with MSG_SPLICE_PAGES.
The bad accounting was introduced by commit 773ba4fe9104 ("ipv6:
avoid partial copy for zc"). Before commit ce650a166335 ("udp6: Fix
__ip6_append_data()'s handling of MSG_SPLICE_PAGES"), the negative
copy value caused -EINVAL to be returned. That later commit allowed
MSG_SPLICE_PAGES to proceed in this case, making the corruption
triggerable.
The non-paged branch sets alloclen to fraglen, which already accounts
for fraggap because datalen does. Bring the paged branch in line by
adding fraggap to alloclen and subtracting it from pagedlen.
After this adjustment, copy no longer collapses to -fraggap on the
paged path, so remove the stale comment describing that old arithmetic.
Since a negative copy is no longer expected for a valid MSG_SPLICE_PAGES
case, remove the MSG_SPLICE_PAGES exception from the negative copy check.

There is no race or external timing condition required.\nPR:L - A normal unprivileged local user can create IPv4 UDP sockets and use UDP_CORK/MSG_MORE/splice or related paged send paths; raw sockets are CAP_NET_RAW-gated but are not needed for the strongest local trigger. This is therefore basic local user privilege, not real administrator privilege.\nUI:N - No victim interaction is required once the attacker can run the local send/splice sequence. The vulnerable skb construction happens synchronously in the attacker-driven socket send path.\nS:U - The impact is within the same kernel security authority as the vulnerable IPv4 networking code. This is not a VM escape, IOMMU bypass, or cross-authority boundary violation.\nC:H - The bug under-allocates/accounting for the linear skb area and can copy attacker-controlled fraggap bytes past skb-\u003eend into trailing skb_shared_info metadata. Kernel memory corruption of this kind is reasonably capable of being developed into information disclosure, so the higher severity confidentiality value is appropriate.\nI:H - The copied fraggap bytes corrupt kernel skb metadata past the intended buffer boundary. This is an out-of-bounds write in kernel heap/networking structures and is scored as high integrity impact.\nA:H - The corrupted skb metadata can crash or destabilize the kernel networking stack, and related negative-copy accounting can also produce severe send-path failure behavior. Kernel crash or oops potential is high availability impact."

Title
virtiofs: fix UAF on submount umount
Summary
In the Linux kernel, the following vulnerability has been resolved:
virtiofs: fix UAF on submount umount
iput() called from fuse_release_end() can Oops if the super block has
already been destroyed. Normally this is prevented by waiting for
num_waiting to go down to zero before commencing with super block shutdown.
This only works, however, for the last submount instance, as the wait
counter is per connection, not per superblock.
Revert to using synchronous release requests for the auto_submounts case,
which is virtiofs only at this time.

Title
media: vidtv: fix NULL pointer dereference in vidtv_mux_push_si
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: vidtv: fix NULL pointer dereference in vidtv_mux_push_si
syzbot reported a general protection fault in
vidtv_psi_ts_psi_write_into [1].
vidtv_mux_get_pid_ctx() can return NULL, but vidtv_mux_push_si() does
not check for this before dereferencing the returned pointer to access
the continuity counter. This leads to a general protection fault when
accessing a near-NULL address.
The root cause is that vidtv_mux_pid_ctx_init() does not check the
return value of vidtv_mux_create_pid_ctx_once() for PMT section PIDs.
If the allocation fails, the PID context is never created, but init
returns success. The subsequent vidtv_mux_push_si() call then gets
NULL from vidtv_mux_get_pid_ctx() and crashes.
Fix both the root cause (add error check in vidtv_mux_pid_ctx_init
for PMT PIDs) and add defensive NULL checks in vidtv_mux_push_si for
all vidtv_mux_get_pid_ctx() calls.
