Description OSIDB Bzimport 2026-08-10 12:38:29 UTC 
In the Linux kernel, the following vulnerability has been resolved:

tcp: fix TIME_WAIT socket reference leak on PSP policy failure

Release the TIME_WAIT socket reference and jump to discard_it
upon PSP policy failure in both IPv4 and IPv6 receive paths.
This prevents a memory leak of tcp_tw_bucket structures.
