CVE-2026-89574

CVE-2026-89574 is a vulnerability in the Linux kernel's device mapper (dm) array component. The root cause is insufficient validation of array block headers during read operations: array_block_check() only verifies blocknr and csum, while element_at() performs unguarded pointer arithmetic driven ...

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate lengths in dlmmiglockreshandler A node receiving a DLMMIGLOCKRES message trusts several fields of the peer-supplied dlmmigratablelockres without validation. numlocks and locknamelen are bounded only on the sending...

CVE-2026-89494

CVE-2026-89494 is a CRITICAL (CVSS 9.8) vulnerability in the OCFS2 Distributed Lock Manager (DLM) within the Linux kernel. The dlm_mig_lockres_handler trusts peer-supplied num_locks and lockname_len fields without validation, leading to an out-of-bounds read (triggering a BUG_ON panic) and a heap...

CVE-2026-81017

CVE-2026-81017 affects the Linux kernel's platform/chrome/sensorhub driver. The root cause is a missing validation of the 8-bit EC-reported sensor number in cros_ec_sensorhub_ring_handler(); the unvalidated value is then used to index sensorhub->batch_state[], an array allocated with only sens...

CVE-2026-81016

This vulnerability affects the Linux kernel's AMD Platform Management Controller (PMC) driver (platform/x86/amd/pmc). The function amd_stb_s2d_init() discards return values from several S2D SMU commands. When the SMU refuses a command, the S2D_PHYS_ADDR_LOW/HIGH return values are ignored, leaving...
