The vulnerability of the devlink_free() function in the net/devlink/core.c module, a implementation of networking functions in the Linux kernel, allows a hacker to cause a service failure.

The vulnerability of the devlinkfree function in the net/devlink/core.c module, which is part of the Linux kernel’s networking functions, stems from the failure to release resources after their useful lifespan has ended. Exploiting this vulnerability could allow an attacker to cause service...

CVE-2026-53261

In the Linux kernel, the following vulnerability has been resolved: devlink: Release nested relation on devlink free devlink relation state is normally released from devlunregister, which calls devlinkrelput. This misses devlink instances that get a nested relation before registration and then fa...
