CVE-2026-74432Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix leak of released call in recvmsg(MSG_PEEK) Fix rxrpc_recvmsg() to also drop the ref it holds on an already-released call if MSG_PEEK is in force (the function holds a ref on the call irrespective of whether MSG_PEEK is specified or not).

Red Hat severity: Low — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-911. Affected Red Hat products: Red Hat Enterprise Linux 10. Red Hat does not currently list a fixing…
