libde265 commit 4d45a6b contains a NULL pointer dereference vulnerability in the NAL parsing path. When de265_push_NAL() is called with a zero-length NAL unit, the resulting NAL_unit may retain a NULL backing buffer, which is subsequently passed as the destination argument to memcpy() in NAL_unit::set_data(). Although the copy length is zero, this violates the nonnull requirement of memcpy() and results in undefined behavior, causing process termination in UBSan-instrumented builds and denial of service.

 https://vulnerability.circl.lu/vuln/usn-8909-1 USN-8909-1 — libde265 vulnerability 2026-10-09T22:30:59.317768+00:00

Affected: Ubuntu:Pro:16.04:LTS: libde265, Ubuntu:Pro:18.04:LTS: libde265, Ubuntu:Pro:20.04:LTS: libde265, Ubuntu:Pro:22.04:LTS: libde265, Ubuntu:24.04:LTS: libde265, Ubuntu:Pro:26.04:LTS: libde265

It was discovered that libde265 did not properly validate certain crafted H.265 bitstreams, leading to a NULL pointer dereference. An attacker could possibly use this issue to cause libde265 to crash, resulting in a denial of service.
