Vulnerability from github – Published: 2022-12-05 18:30 – Updated: 2025-04-14 18:31

Details

A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition.

Severity ?

5.5 (Medium)
