CVSS v3.1 |
| IBM WebSphere Extreme Scale 8.6.1.0 through 8.6.1.6 could allow an adjacent attacker to cause a denial of service due to improper validation in the XDF decoder. The application processes deeply nested Protocol Buffers messages and attacker-controlled length prefixes without sufficient bounds checking, which may allow an attacker on the same network to trigger a StackOverflowError or OutOfMemoryError, resulting in a crash of the WebSphere Application Server JVM. |
| IBM InfoSphere Information Server 11.7.0.0 through 11.7.1.6 is affected by an information disclosure vulnerability. |
| IBM Langflow OSS 1.0.0 through 1.10.0 could allow arbitrary code execution due to improper validation of flow nodes with missing or empty component type fields. |
| Insertion of sensitive information into sent data in the AI Agent job API in Devolutions PowerShell Universal 2026.2.0 allows an authenticated user with AI Agent read access to obtain reusable, potentially higher-privileged authentication tokens via App Tokens serialized in plaintext in job API responses. |
| HCL Traveler for Microsoft Outlook (HTMO) is susceptible to vulnerabilities due to .NET Framework 4.5 being out of service. Since .NET Framework 4.5 has reached end-of-life and no longer receives security updates, it may expose the application to publicly known security weaknesses through vulnerable third-party components. |
| In the Linux kernel, the following vulnerability has been resolved:
nilfs2: reject zero bd_oblocknr in nilfs_ioctl_mark_blocks_dirty()
nilfs_ioctl_mark_blocks_dirty() uses bd_oblocknr to detect dead blocks
by comparing it with the current block number bd_blocknr. If they differ,
the block is considered dead and skipped.
However, bd_oblocknr should never be 0 since block 0 typically stores the
primary superblock and is never a valid GC target block. A corrupted ioctl
request with bd_oblocknr set to 0 causes the comparison to incorrectly
match when the lookup returns -ENOENT and sets bd_blocknr to 0, bypassing
the dead block check and calling nilfs_bmap_mark() on a non-existent
block. This causes nilfs_btree_do_lookup() to return -ENOENT, triggering
the WARN_ON(ret == -ENOENT).
Fix this by rejecting ioctl requests with bd_oblocknr set to 0 at the
beginning of each iteration.

soc/tegra: cbb: Fix cross-fabric target timeout lookup
When a fabric receives an error interrupt, the error may have
occurred on a different fabric. The target timeout lookup was using
the wrong base address (cbb->regs) with offsets from a different
fabric's target map, causing a kernel page fault.
Unable to handle kernel paging request at virtual address ffff80000954cc00
pc : tegra234_cbb_get_tmo_slv+0xc/0x28
Call trace:
tegra234_cbb_get_tmo_slv+0xc/0x28
print_err_notifier+0x6c0/0x7d0
tegra234_cbb_isr+0xe4/0x1b4
Add tegra234_cbb_get_fabric() to look up the correct fabric device
using fab_id, and use its base address for accessing target timeout
registers. |
| In the Linux kernel, the following vulnerability has been resolved:
x86/kexec: Push kjump return address even for non-kjump kexec
The version of purgatory code shipped by kexec-tools attempts to look above
the top of its stack to find a return address for a kjump, even in a non-kjump
kexec.
After the commit in Fixes: the word above the stack might not be there,
leading to a fault (which is at least now caught by my exception-handling code
in kexec).
That commit fixed things for the actual kjump path, but no longer
"gratuitously" pushes the unused return address to the stack in the non-kjump
path. Put that *back* in the non-kjump path, to prevent purgatory from
crashing when trying to access it. |
| In the Linux kernel, the following vulnerability has been resolved:
Revert "drm/xe: Skip exec queue schedule toggle if queue is idle during suspend"
This reverts commit 8533051ce92015e9cc6f75e0d52119b9d91610b6.
The idle-skip optimization bypasses GuC suspend, so the GPU may not
perform the context switch that flushes TLB entries for invalidated
userptr VMAs. In LR/preempt-fence VM mode, this can lead to missed TLB
invalidation and page faults during userptr invalidation tests.
Restore unconditional schedule toggling on suspend so the context-switch
TLB flush is always performed.
This optimization will be reintroduced with a fix that does not skip
suspend in LR/preempt-fence VM mode.

| In the Linux kernel, the following vulnerability has been resolved:
VFS: fix possible failure to unlock in nfsd4_create_file()
atomic_create() in fs/namei.c drops the reference to the dentry
when it returns an error.
This behaviour was imported into dentry_create() so that it
will drop the reference if an error is returned from atomic_create(),
though not if vfs_create() returns an error (in the case where
->atomic_create is not supported).
The caller - nfsd4_create_file() - is made aware of this by checking
path->dentry, which will either be a counted reference to a dentry, or
an error pointer.
However the change to use start_creating()/end_creating() (which landed
shortly before the dentry_create() change landed, though was likely
developed around the same time) means that nfsd4_create_file() *needs* a
valid dentry so that it can unlock the parent.
The net result is that if NFSD exports a filesystem which uses
->atomic_create, and if a call to ->atomic_create returns an error, then
nfsd4_create_file() will pass an error pointer to end_creating()
and the parent will not be unlocked.
Fix this by changing dentry_create() to make sure path->dentry is always
a valid dentry, never an error-pointer. The actual error is already
returned a different way.
Note that if ->atomic_create() returns a different dentry (which may not
be possible in practice) we are guaranteed (because it is only ever
provided by d_spliace_alias()) that it will have the same d_parent and
so it will have the same effect when passed to end_creating(). |
| In the Linux kernel, the following vulnerability has been resolved:
net: add pskb_may_pull() to skb_gro_receive_list()
skb_gro_receive_list() calls skb_pull(skb, skb_gro_offset(skb)) without
first ensuring the data is in the linear area via pskb_may_pull(). When
the skb arrives via napi_gro_frags(), skb_headlen can be 0 (all data in
page fragments) while skb_gro_offset is non-zero (after IP+TCP header
parsing). The skb_pull() then decrements skb->len by skb_gro_offset
but skb->data_len stays unchanged, hitting BUG_ON(skb->len < skb->data_len)
in __skb_pull().
The UDP fraglist GRO path already contains this guard at
udp_offload.c:749. Adding it to skb_gro_receive_list() itself provides
centralized protection for all callers (TCP, UDP, and any future
protocols), and ensures the precondition of skb_pull() is satisfied
before it is called.
On pskb_may_pull() failure, set NAPI_GRO_CB(skb)->flush = 1 so the
skb is not held as a new GRO head and is instead delivered through the
normal receive path, matching the UDP handling. |
| In the Linux kernel, the following vulnerability has been resolved:
net: mvpp2: limit XDP frame size to the RX buffer
mvpp2 has short and long BM pools, and short pool buffers can be smaller
than PAGE_SIZE. The XDP path nevertheless initializes every xdp_buff with
PAGE_SIZE as frame size.
XDP helpers use frame_sz to validate tail growth and to derive the hard
end of the data area. Advertising PAGE_SIZE for short buffers can let
bpf_xdp_adjust_tail() grow a packet past the real allocation, corrupting
memory or later tripping skb tailroom checks.
Initialize the XDP buffer with bm_pool->frag_size so XDP tailroom matches
the actual buffer backing the packet. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: nv: Fix handling of XN[0] when !FEAT_XNX
XN has already been extracted from its bitfield position so using
FIELD_PREP() on the mask that clears XN[0] is completely broken, having
the effect of unconditionally granting execute permissions...
Fix the obvious mistake by manipulating the right bit. |
| In the Linux kernel, the following vulnerability has been resolved:
ovl: keep err zero after successful ovl_cache_get()
ovl_iterate_merged() stores PTR_ERR(cache) in err before checking
IS_ERR(cache). On success err holds the truncated cache pointer and
can be returned as a bogus non-zero error.
The syzbot reproducer reaches this through overlay-on-overlay readdir:
getdents64
iterate_dir(outer overlay file)
ovl_iterate_merged()
ovl_cache_get()
ovl_dir_read_merged()
ovl_dir_read()
iterate_dir(inner overlay file)
ovl_iterate_merged()
Only compute PTR_ERR(cache) on the error path. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/ethosu: fix arithmetic issues in dma_length()
dma_length() derives DMA region usage from command stream values and
updates region_size[]:
len = ((len + stride[0]) * size0 + stride[1]) * size1
region_size[region] = max(..., len + dma->offset)
Several arithmetic issues can corrupt the derived region size:
- signed stride values may underflow when added to len
- intermediate multiplications may overflow
- len + dma->offset may overflow during region_size updates
- dma_length() error returns were not validated by the caller
region_size[] is later used by ethosu_job.c to validate command stream
accesses against GEM buffer sizes. Arithmetic wraparound can therefore
under-report region usage and bypass the bounds validation.
Fix by validating signed additions, using overflow helpers for
multiplications and offset updates, and propagating dma_length()
failures to the caller. |
| In the Linux kernel, the following vulnerability has been resolved:
memcg: use round-robin victim selection in refill_stock
Harry Yoo reported that get_random_u32_below() is not safe to call in the
nmi context and memcg charge draining can happen in nmi context.
More specifically get_random_u32_below() is neither reentrant- nor
NMI-safe: it acquires a per-cpu local_lock via local_lock_irqsave() on the
batched_entropy_u32 state. An NMI that lands on a CPU mid-update of the
ChaCha batch state and recurses into the random subsystem would corrupt
that state. The memcg_stock local_trylock prevents re-entry on the percpu
stock itself, but cannot protect an unrelated subsystem's per-cpu lock.
Replace the random pick with a per-cpu round-robin counter stored in
memcg_stock_pcp and serialized by the same local_trylock that already
guards cached[] and nr_pages[]. No atomics, no random calls, no extra
locks needed. |
| In the Linux kernel, the following vulnerability has been resolved:
net/rds: Restrict use of RDS/IB to the initial network namespace
Prevent using RDS/IB in network namespaces other than the initial one.
The existing RDS/IB code will not work properly in non-initial network
namespaces. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/riscv: Add IOTINVAL after updating DDT/PDT entries
Add riscv_iommu_iodir_iotinval() to perform required TLB and context cache
invalidations after updating DDT or PDT entries, as mandated by the RISC-V
IOMMU specification (Section 6.3.1 and 6.3.2). |
| In the Linux kernel, the following vulnerability has been resolved:
memory: tegra124-emc: Fix dll_change check
The code checking whether the specified memory timing enables DLL
in the EMRS register was reversed. DLL is enabled if bit A0 is low.
Fix the check. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSD: fix nfs4_file access extra count in nfsd4_add_rdaccess_to_wrdeleg
In nfsd4_add_rdaccess_to_wrdeleg, if fp->fi_fds[O_RDONLY] is already
set by another thread, __nfs4_file_get_access should not be called
to increment the nfs4_file access count since that was already done
by the thread that added READ access to the file. The extra fi_access
count in nfs4_file can prevent the corresponding nfsd_file from being
freed.
When stopping nfs-server service, these extra access counts trigger a
BUG in kmem_cache_destroy() that shows nfsd_file object remaining on
__kmem_cache_shutdown.
This problem can be reproduced by running the Git project's test
suite over NFS. |
