UBUNTU-CVE-2026-97912

In the Linux kernel, the following vulnerability has been resolved: accel: ethosu: Ensure SRAM size is 0 on mapping failure On a mapping failure of the SRAM, the SRAM size is left as non-zero. The probe will succeed as the error return is not checked since having SRAM is not a hard requirement. T...

In the Linux kernel, the following vulnerability has been resolved: bpf: don't downgrade half-dead scalar zero spills to STACKZERO states.c:cleanfuncstate can downgrade scalar zero spill to STACKZERO in the following case: u64 r10 - 8 = 0; ... checkpoint ... r1 = u32 r10 - 4; ... no reads from...

UBUNTU-CVE-2026-97571

In the Linux kernel, the following vulnerability has been resolved: bnxten: Propagate TPA buffer allocation failures in bnxtqueuememalloc bnxtalloconetpainfodata returns -ENOMEM as soon as one allocation fails. This leaves the remaining rxr-rxtpa entries zeroed. bnxtqueuememalloc discards that...

CVE-2026-98145

The Linux kernel contains a vulnerability in the accel/amdxdna driver where a command chain with a command_count of zero improperly passes payload length checks. Because the struct_size calculation only accounts for the header, the fill loop is skipped, resulting in the submission of a zero-lengt...

CVE-2026-98145 accel/amdxdna: reject a command chain that carries no commands

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: reject a command chain that carries no commands A chain whose commandcount is zero passes the payload length check, because structsizepayload, data, 0 is just the header. The fill loop then does not run, so offset...

CVE-2026-98137

In the Linux kernel, the following vulnerability has been resolved: ntfs: treat any nonzero dio zero-range return as an error ntfsdiozerorange returns either 0 or a negative errno from blkdevissuezeroout; it never returns a positive value. The zeroing failure check in ntfsattrfallocate therefore...

CVE-2026-98132

A flaw exists in the Linux kernel 's Berkeley Packet Filter (BPF) verifier, specifically within the states.c:__clean_func_state() function. The vulnerability occurs when the verifier incorrectly downgrades a half-dead scalar zero spill to STACK_ZERO because a portion of the stack memory is consid...

CVE-2026-98126

In the Linux kernel, the following vulnerability has been resolved: smb/client: validate new EOF for zero range When FALLOCFLZERORANGE is used without FALLOCFLKEEPSIZE, smb3zerorange may extend EOF without checking RLIMITFSIZE, allowing the file to grow beyond the caller's file-size limit. Fix th...
