CVE-2026-89495

Linux kernel (ocfs2/dlm subsystem) is vulnerable to a heap out-of-bounds write in dlm_migrate_request_handler(). A peer-supplied namelen field (u8) from a DLM_MIGRATE_REQUEST message is passed unchecked to dlm_init_mle(), which memcpy()s it into a fixed 32-byte mname[] array, allowing up to ~215 ...

CVE-2026-89494

CVE-2026-89494 is a Linux kernel vulnerability in the OCFS2 DLM subsystem, specifically in dlm_mig_lockres_handler. A node receiving a DLM_MIG_LOCKRES message trusts peer-supplied num_locks and lockname_len fields without validation. This leads to two distinct issues: an out-of-bounds read in dlm...

CVE-2026-89436

CVE-2026-89436 affects the Linux kernel 's platform/x86: panasonic-laptop driver. The root cause is an off-by-one heap overflow : acpi_pcc_retrieve_biosdata() unconditionally writes a trailing sentinel at pcc->sinf[hkey->package.count], but the array is allocated with only pcc->num_sifr ...

CVE-2026-81014

CVE-2026-81014 is a heap out-of-bounds read in the Linux kernel's platform/x86: hp-bioscfg driver, affecting the sk_store() and kek_store() sysfs write handlers. Both functions strip a trailing newline from user input and allocate a key buffer of size length (one byte shorter), but then pass the ...
