• Severity: medium (CVSS 4.7 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.6% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-02-21 · updated 2026-08-04
• Weakness: CWE-362

Description

In the Linux kernel, the following vulnerability has been resolved: tls: fix race between tx work scheduling and socket close Similarly to previous commit, the submitting thread (recvmsg/sendmsg) may exit as soon as the async crypto handler calls complete(). Reorder scheduling the work before calling complete(). This seems more logical in the first place, as it's the inverse order of what the submitting thread will do.

Affected products

• Linux kernel: from 4.20.0 before 6.6.18; from 6.7.0 before 6.7.6 — fixed in 6.6.18, 6.7.6

How to fix

Upgrade to a fixed version: Linux kernel 6.6.18, 6.7.6. Check the vendor advisory for mitigations.
