CVE-2026-99137

The Linux kernel contains a vulnerability in the CIFS filesystem where the i_size is incorrectly updated in cifs_do_truncate when a cached handle is missing. Specifically, if find_writable_file() returns null, the system might set i_size to 0 even if the server-side truncation fails, leading to a...

CVE-2026-99111

The Linux kernel contains a vulnerability in the SMB client where concurrent writes and O_TRUNC operations could lead to data corruption . Specifically, the cifs_do_truncate() function failed to hold the i_rwsem or invalidate_lock while flushing dirty pages and truncating files. This allowed conc...
