CVE-2022-49344

Severity CVSS v4.0:
Pending analysis
Type:
CWE-362 Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
Publication date:

Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> af_unix: Fix a data-race in unix_dgram_peer_wake_me().<br /> <br /> unix_dgram_poll() calls unix_dgram_peer_wake_me() without `other`&amp;#39;s<br /> lock held and check if its receive queue is full. Here we need to<br /> use unix_recvq_full_lockless() instead of unix_recvq_full(), otherwise<br /> KCSAN will report a data-race.
