CVE-2026-52941

A flaw was found in the Linux kernel's net/smc module. An unprivileged local user could trigger a null pointer dereference by performing sendmsg or recvmsg operations on an SMC-D Shared Memory Communications - Direct socket while the smcmsgevent tracepoint is enabled. This can lead to a general...

CVE-2026-52938

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF storage. A race condition can occur where a storage element is accessed after its associated map has been deallocated, leading to a null pointer dereference. This can cause a kernel crash, resulting in a Denial of Service DoS for t...

CVE-2026-52922

A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking module. This vulnerability occurs because the batadvdatforwarddata function fails to validate the success of a memory allocation operation. An attacker could exploit this by triggering a scenario where t...

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...
