CVE-2026-47328 Invalid pointer deallocation in Ubuntu Linux AppArmor notification handling

Ubuntu Linux 6.8, 6.17 and 7.0 contain AppArmor SAUCE patches which incorrectly attempt to free a pointer which was not previously kmallocd, while at the same time leaking allocated memory. The bug can be triggered by an unprivileged local user and can result in the corruption of slab metadata an...

CVE-2026-47328

The CVE affects Ubuntu Linux versions 6.8, 6.17 and 7.0, where AppArmor SAUCE patches incorrectly free a pointer that was not kmalloc’d and leak memory.
