FKIE_CVE-2024-35908

Vulnerability from fkie_nvd - Published: 2024-05-19 09:15 - Updated: 2025-09-24 18:52
Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: tls: get psock ref after taking rxlock to avoid leak At the start of tls_sw_recvmsg, we take a reference on the psock, and then call tls_rx_reader_lock. If that fails, we return directly without releasing the reference. Instead of adding a new label, just take the reference after locking has succeeded, since we don't need it before.
