SUSE 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...

CVE-2026-74354

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. A local attacker could exploit a locking issue within the zappages function. This vulnerability arises because zapvmarange requires a specific memory map lock mmaplock that, when acquired under certain conditions, can le...

CVE-2026-45837: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix use-after-free in arenavmclose on fork arenavmopen only bumps vml-mmapcount but never registers the child VMA in arena-vmalist. The vml-vma always points at the parent VMA, so after parent munmap the pointer dangles. If...
