CVE-2026-99113 Oct 28, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: zero the FS_OBJECT_ID_INFORMATION buffer before filling it in
smb2_get_info_filesystem() reports 64 bytes for FS_OBJECT_ID_INFORMATION,
that is the whole of struct object_id_info, but writes only 46 of them:
- objid[] is 16 bytes, and when the volume UUID is not available only
sizeof(stfs.f_fsid) (8) bytes are copied into it;
- extended_info.version_string[] is STRING_LENGTH (28) bytes, and only
strlen("1.1.0")
