Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds write (CVE-ID: CVE-2026-79900)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to cause a denial of service.

The vulnerability exists due to an out-of-bounds write in boks_ksllogsd KSL checksum initialization when processing an authenticated KSL start message containing an oversized MD field. A remote user can supply an oversized OpenSSL-recognized digest name to write beyond the end of a heap allocation and cause a denial of service.

The digest name is validated as recognized by OpenSSL but is not validated to fit in the fixed 16-byte checksum context field.
