CVE-2026-98114

The Linux kernel 's ksmbd component is vulnerable to an issue where the parse_dacl() function silently accepts truncated ACEs and allocation failures. This allows set_info_sec() to proceed with an incomplete ACL conversion, potentially leading to incorrect permission handling. The fix involves re...

CVE-2026-97559

The Linux kernel contains a vulnerability in the SMB client where the functions replace_sids_and_copy_aces() and set_chmod_dacl() incorrectly use a u16 accumulator to track DACL size. This causes an integer wraparound when the rewritten DACL exceeds 64K (specifically reaching a wraparound with 86...
