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-2026-74354
CVE-2026-74354 : In the Linux kernel, a vulnerability in the BPF zap_pages path is resolved by changing how mmap_lock is taken for zap_vma_range(). The root cause is that zap_vma_range() requires the owning mm’s mmap_lock to be held, and taking mmap_read_lock under arena->lock could AB-BA agai...

CVE-2022-50128
The PT-2025-26054 entry details a Linux kernel vulnerability in the android binder component: saving a pointer to a VMA outside the mmap lock can lead to stale pointers after VMA teardown. Affected software is the Linux kernel (binder component). The root cause is unsafe VMA pointer handling in t...
