CVE-2026-89629

CVE-2026-89629 affects the Linux kernel in the HID corsair-void driver . The root cause is an out-of-bounds read triggered by malformed status and firmware events whose size was not validated before being read. The fix adds a size check and emits a warning on unexpected values to prevent the read...

CVE-2026-89617

A vulnerability in the Linux kernel NTFS3 filesystem driver (fs/ntfs3) allows a local attacker to craft a malicious NTFS log file where a tampered lcns_follow field in a DIR_PAGE_ENTRY causes an out-of-bounds write during log replay. The root cause is that check_rstbl() validates table bookkeepin...
