CVE-2026-74335

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability occurs in the bpftaskfromvpid function when a cgroupskb program, running in a soft interrupt, attempts to look up a task that is in the process of exiting. If the task's process ID PID namespace is...

The vulnerability of the bpf component in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the bpf component in the Linux operating system’s kernel is related to errors during the update of the link counters. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-74338

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. A local attacker could bypass security checks by directly using the bpf2 system call to load a sleepable BPFLSMCGROUP program. This could lead to a kernel crash, resulting in a Denial of Service DoS on the affected syste...

CVE-2026-74360

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. The bpfmapelem iterator does not properly enforce exclusivity checks for certain maps, allowing it to bind to an exclusive map. This oversight exposes the map's value as a writable buffer. A local attacker could leverage...

CVE-2026-74305

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability allows a program without cgroup storage to bypass compatibility checks when bridging tail call chains. This could enable unintended interactions between programs with and without cgroup storage,...

CVE-2026-74337

A flaw was found in the Linux kernel, specifically within the BPF Berkeley Packet Filter subsystem. This vulnerability allows NMI Non-Maskable Interrupt and tracepoint BPF programs to re-enter certain internal locks, known as LRU Least Recently Used locks, while they are already held. This re-ent...

CVE-2026-74258
