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...

AZL-96018 CVE-2026-74338 affecting package kernel 6.6.157.1-1
In the Linux kernel, the following vulnerability has been resolved: bpf: Reject sleepable BPFLSMCGROUP programs at load time The cgroup shim runs under rcureadlockdontmigrate, so we should not attach any sleepable BPF programs there. Add support to the verifier to explicitly reject attempts to lo...

CVE-2026-74342
The CVE-2026-74342 entries describe a Linux kernel issue in kernfs where the LSM security hook runs before kn->__parent and kn->dir.root are initialized, causing a NULL-pointer dereference in kernfs_root(kn) (triggered during the first cgroup mkdir under /sys/fs/cgroup on SELinux-enabled sy...
CVE-2026-74338
CVE-2026-74338 concerns the Linux kernel: a BPF_LSM_CGROUP sleepable program could be loaded in a context where sleeping is disallowed, triggering a BUG from sleeping in an invalid context during file_open. The fix adds verifier support to reject loading sleepable BPF_LSM_CGROUP programs destined...
