CVE-2026-31705
The CVE-2026-31705 issue affects the ksmbd component of the Linux kernel, where an out-of-bounds write occurs in smb2_get_ea() during EA alignment padding. After writing each EA entry, a 4-byte alignment padding is applied with memset() unconditionally, potentially overwriting adjacent kernel hea...
