CVE-2026-99109 Oct 28, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
smb: client: reject SetEA requests that do not fit the request buffer
CIFSSMBSetEA() copies the caller's extended attribute value into the
SMB request buffer without checking that it fits. The requirement is
stated in the source but was never implemented:
/*BB add length check to see if it would fit in
negotiated SMB buffer size BB */
/* if (ea_value_len > buffer_size - 512 (enough for header)) */
if (ea_value_len)
