CVE-2026-52919

A flaw was found in the batman-adv module of the Linux kernel. During the shutdown process of the tpmeter sender, an atomic counter can underflow due to multiple decrements. This can cause the sender kernel thread to loop indefinitely, leading to a use-after-free vulnerability if the associated...

CVE-2026-52939

A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS component. An unprivileged local user can trigger a kernel panic by sending a specially crafted atomic control message cmsg over an active RDS/InfiniBand IB connection. This issue is caused by improper handling of masked atomic...
