CVE-2026-53008

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A race condition exists between the ice free tx tstamp ring() and ice tx map() functions. The ice free tx tstamp ring() function clears the ICE TX FLAGS TXTIME flag after setting the tstamp ring to NULL. This sequence allows a concurrent call to ice tx map() on another CPU to dereference the tstamp ring while it is NULL, resulting in a NULL pointer dereference.

Recommendations As a temporary mitigation, restrict the use of the ice free tx tstamp ring() and ice tx map() functions if possible. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
