CVE-2022-2959 – Linux Kernel Watch Queue Race Condition Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-2959
A race condition was found in the Linux kernel's watch queue due to a missing lock in pipe_resize_ring(). The specific flaw exists within the handling of pipe buffers. The issue results from the lack of proper locking when performing operations on an object. This flaw allows a local user to crash the system or escalate their privileges on the system. Se ha encontrado una condición de carrera en la cola de vigilancia del kernel de Linux debido a una falta de bloqueo en la función pipe_resize_ring(). • https://github.com/torvalds/linux/commit/189b0ddc245139af81198d1a3637cac74f96e13a https://security.netapp.com/advisory/ntap-20230214-0005 https://www.zerodayinitiative.com/advisories/ZDI-22-1165 https://access.redhat.com/security/cve/CVE-2022-2959 https://bugzilla.redhat.com/show_bug.cgi?id=2103681 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-667: Improper Locking •
