CVE-2026-53291

CVE-2026-53291 affects the Linux kernel ALSA hda/conexant driver. The root cause is the ignored return value from snd_hda_jack_detect_enable_callback() in cx_probe(); if the call fails, an error pointer is returned and not checked, potentially leading to a crash when jack events are handled. The ...

CVE-2026-52963

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA USB audio driver. The driver's handling of MIDI Musical Instrument Digital Interface endpoint descriptors did not properly bound scans, allowing it to read beyond the intended memory buffer. This out-of-bounds read coul...

CVE-2026-53110

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter JIT Just-In-Time compiler for the s390x architecture. The system's Application Binary Interface ABI requires that unsigned arguments and return values be zero-extended. However, the BPF JIT compiler incorrectly performed only sign...

CVE-2026-53038

A flaw was found in the Linux kernel's Integrity Measurement Architecture IMA subsystem. When handling unsupported Trusted Platform Module TPM hash algorithms, the imafs component incorrectly accesses a hash algorithm name array, leading to a read out-of-bounds. This vulnerability could allow a...

Security update for the Linux Kernel

The SUSE Linux Enterprise 15 SP5 kernel was updated to fix various security issues The following security issues were fixed: CVE-2025-10263: arm64: errata: Mitigate TLBI errata on various Arm CPUs bsc1266290. CVE-2025-68324: scsi: imm: Fix use-after-free bug caused by unfinished delayed work...

CVE-2026-53277

A flaw was found in the Kernel-based Virtual Machine KVM component of the Linux kernel on arm64 architectures. This vulnerability occurs because certain page table walk operations, used in fault injection and Address Translation AT emulation, do not properly acquire a Sleepable Read-Copy Update...
