CVE-2026-53327
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
debugobjects: Do not fill_pool() if pi_blocked_on
On RT enabled kernels, fill_pool() ends up calling rtlock_lock(), which asserts if current::pi_blocked_on is set, because a task can obviously only block on one lock as otherwise the priority inheritenace chain gets corrupted.
Prevent this by expanding the conditional to take current::pi_blocked_on into account.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
