CVE-2026-52951

A flaw was found in the Linux kernel's drm/xe/dma-buf subsystem. This vulnerability involves race conditions when handling the invalidatemappings hook, particularly during buffer object initialization and attachment. An attacker, by triggering specific sequences of operations, could exploit these...

CVE-2026-53008

A flaw was found in the Linux kernel. A race condition exists in the ice network driver's TX timestamp ring cleanup, specifically between the icefreetxtstampring and icetxmap functions. This vulnerability could allow a local attacker to trigger a null pointer dereference, leading to a system cras...

CVE-2026-53064

A flaw was found in the Linux kernel's device-mapper dm-cache component. When dm-cache operates in passthrough mode, a race condition can occur during concurrent write operations to the same cached block. This can lead to a null-pointer dereference in the invalidatecomplete function, potentially...

CVE-2026-53111

A flaw was found in the Linux kernel. The bpflwtxmitpushencap helper in the Berkeley Packet Filter BPF subsystem attempts to access an uninitialized network device structure during certain test runs. A local user can exploit this null pointer dereference by executing the bpflwtpushipencap functio...
