CVE-2026-98454

A flaw in the Linux kernel SMB client allows a malicious SMB server to trigger out-of-bounds memory reads by sending malformed create context responses. The issue stems from smb2_parse_contexts() failing to limit each record to its Next field, potentially exposing bytes beyond the current context...

CVE-2026-98455

The Linux kernel contains a vulnerability in the Bluetooth RFCOMM stack where a NULL pointer dereference occurs in the RFCOMM_CONNINFO getsockopt handler. When BT_DEFER_SETUP is enabled, the dlc->defer_setup flag remains set even if the session is cleared during rfcomm_recv_disc(). Consequentl...

CVE-2026-98453

The Linux kernel contains a vulnerability in the SMB client where SMB2_open() incorrectly handles the lifecycle of a remote handle. Specifically, the function accounts for a successful CREATE response as a remote open before parsing the create contexts. If smb2_parse_contexts() encounters malform...

CVE-2026-98452

The Linux kernel contains a vulnerability in the SMB client where open_cached_dir() fails to properly handle compound requests. Specifically, if a CREATE succeeds but a subsequent command in the compound request returns an error, the system fails to retain the CREATE FID for proper cleanup using ...
