CVE-2026-97555

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix heap overflow in DACL owner/group rewrite When idmodetocifsacl rewrites an existing DACL, it allocates a buffer sized according to the on-disk DACL length reported by daclptr-size. However, replacesidsandcopyaces...

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...
