CVE-2026-98394

A flaw was found in the Linux kernel's UNIX domain socket afunix implementation. When a blocking receive operation is performed using a zero-length buffer and the peek flag on a socket where the last queued message contains out-of-band OOB data, the kernel fails to return properly. A local attack...

CVE-2026-98394

The Linux kernel contains a vulnerability in af_unix where recv(0, MSG_PEEK) triggers a busy-wait in unix_stream_read_generic(). This occurs when a blocking recv() is called and the final socket buffer (skb) in the queue is an MSG_OOB skb, but manage_oob() returns NULL for a 0-length buffer. The ...

CVE-2026-109832 Gnome-remote-desktop: busy-wait dos in vnc tls i/o handlers (gnutls_e_again / gnutls_e_interrupted)

A flaw was found in gnome-remote-desktop as shipped in Red Hat Enterprise Linux. In the VNC TLS I/O handlers, retryable GnuTLS results GNUTLSEAGAIN and GNUTLSEINTERRUPTED are handled with an unbounded busy loop instead of yielding to the event loop. A remote attacker who can reach an enabled VNC...
