UBUNTU-CVE-2026-72456

In the Linux kernel, the following vulnerability has been resolved: apparmor: release exe file resources on path failure getcurrentexepath takes both an exefile reference and a path reference before resolving the path name. If aapathname failed, it returned immediately and leaked both references...

CVE-2026-72461

Vulnerability CVE-2026-72461 affects the Linux kernel with AppArmor: a refcount leak in updating the sk_ctx. Root cause: update_sk_ctx() transfers the plabel reference but also unconditionally releases it in the caller; the fix is to obtain a proper reference and avoid double-free. Affected compo...

CVE-2026-72462

The CVE-2026-72462 entries describe a race in AppArmor unix socket mediation on Linux kernels where holding a reference to peer_sk is insufficient to guarantee access to the peer path. The race occurs when accessing the peer path outside the state lock, potentially conflicting with unix_release_s...

CVE-2026-72460

CVE-2026-72460 affects the Linux kernel’s AppArmor path: aa_change_profile() builds a replacement label with fn_label_build_in_scope() before the no_new_privs subset check, and the build helper may return NULL/ERR_PTR, with the result previously passed to aa_label_is_unconfined_subset() without I...

In the Linux kernel, the following vulnerability has been resolved: apparmor: aalabelalloc use aalabelfree on alloc failure aalabelalloc allocates a secid before allocating or taking the label proxy. If the later proxy step fails, the error path only freed the label memory, leaking any resources...

CVE-2026-72459

CVE-2026-72459 concerns the Linux kernel AppArmor path: in aa_label_alloc(), a secid is allocated before creating the label proxy. If the subsequent proxy step fails, the error path currently frees only the label memory, leaking resources initialized by aa_label_init(). The fix is to call aa_labe...

CVE-2026-72458

Summary: CVE-2026-72458 affects the Linux kernel (apparmor module) and is due to a NULL pointer dereference in unpack_pdb when pdb->dfa can be NULL if unpack_dfa fails. This could lead to a dereference vulnerability in apparmor paths. What’s affected: Linux kernel components implementing appar...
