An official fix is available, so this entry is kept for 30 days and then removed automatically.

01

Who is affected

All Linux kernel users, regardless of distribution, are potentially affected until they apply the latest kernel update that contains the patch.

02

Real-world impact

An attacker could trigger a denial‑of‑service by sending crafted TLS traffic that exploits the race, causing the kernel to crash or behave unpredictably, which could lead to service interruption.

03

Why this severity

The CVSS score of 9.8 reflects the vulnerability’s high impact (complete compromise of confidentiality, integrity, and availability) combined with its ease of exploitation: it requires no special privileges, no user interaction, and can be triggered remotely over the network.

04

What to do about it
