In the Linux kernel, the following vulnerability has been resolved: bpf: reject direct access to nullable PTRTOBUF pointers checkmemaccess matches PTRTOBUF via basetype which strips PTRMAYBENULL, allowing direct dereference without a null check. Map iterator ctx-key and ctx-value are PTRTOBUF |...

UBUNTU-CVE-2026-43416

In the Linux kernel, the following vulnerability has been resolved: powerpc, perf: Check that current-mm is alive before getting user callchain It may happen that mm is already released, which leads to kernel panic. This adds the NULL check for current-mm, similarly to commit 20afc60f892d "x86,...

CVE-2026-43321

The CVE-2026-43321 issue is in the Linux kernel BPF subsystem, where indirect jumps did not correctly mark the live registers for a gotox rX, leaving the affected register state unchecked. When the kernel fails to mark registers as used, it can enable manipulation of kernel state and potentially ...

CVE-2026-43306

CVE-2026-43306 affects the Linux kernel due to bpf: crypto: Use the correct destructor kfunc type. With CONFIG_CFI enabled, indirect calls must match the target function’s pointer type. In the reported case, a CFI failure occurred at bpf_obj_free_fields while freeing a BPF crypto context, signali...
