CVE-2026-72112

A flaw was found in the Linux kernel's iouring/bpf-ops component. This vulnerability allows a local attacker with specific capabilities CAPBPF and CAPPERFMON to re-register an already-bound operation, leading to a use-after-free of freed executable memory. This could result in arbitrary code...

CVE-2026-72111

A flaw was found in the Linux kernel's BPF verifier. When processing a context load of an LSM hook return value, the markregs32range function incorrectly intersects new register bounds with stale ones, rather than replacing them. This can lead to a mismatch between the verifier's understanding of...

CVE-2026-72110

A flaw was found in the Linux kernel's BPF/fork component. A local user, by initiating a fork operation from a process within a task storage map, can trigger a condition where the bpfstorage is not properly initialized. This can lead to a Use-After-Free UAF vulnerability, which occurs when the...

CVE-2026-68462

A flaw was found in the Linux kernel. The BPF Berkeley Packet Filter verifier, responsible for ensuring the safety of BPF programs, incorrectly processed negative constant offsets when accessing buffer pointers. This oversight could allow a local attacker to craft a malicious BPF program that...

CVE-2026-74371

In the Linux kernel, the following vulnerability has been resolved: bpf: fix BPFPROGQUERY OOB write and cgroup backward compat BPFPROGQUERY writes back the 'query.revision' field unconditionally to userspace. If userspace passes a smaller 'bpfattr' structure e.g. 40 bytes, which was the layout...

CVE-2026-74363

In the Linux kernel, the following vulnerability has been resolved: bpf: fix UAF by restoring RCU-delayed inode freeing in bpffs commit 4f375ade6aa9 "bpf: Avoid RCU context warning when unpinning htab with internal structs" moved inode cleanup from -freeinode into -destroyinode to avoid sleeping ...

CVE-2026-74360

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject exclusive maps for bpfmapelem iterators Exclusive maps aka exclproghash are meant to be reachable only from the single program whose hash matches. This is enforced by checkmapprogcompatibility when the map is referenc...

CVE-2026-74354

In the Linux kernel, the following vulnerability has been resolved: bpf: Take mmaplock in zappages zapvmarange requires the owning mm's mmaplock to be held. Taking mmapreadlock under arena-lock would AB-BA against arenavmclose and arenamapmmap, both of which run with mmapwritelock held and then...
