CVE-2026-45837
The CVE-2026-45837 issue affects the Linux kernel BPF arena memory management during fork. The root cause is that arena_vm_open() bumps mmap_count but does not register the child VMA in arena->vma_list, leaving vml->vma to point to the parent VMA. After the parent unmaps, a use-after-free c...

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix use-after-free in arena vm close on fork arena vm open only bumps vml-mmap count but never registers the child VMA in arena-vma list. The vml-vma always points at the parent VMA, so after parent munmap the pointer dangle...

CVE-2026-43433
A flaw was found in the Linux kernel's rustbinder component. If a local process gains the ability to write to its own virtual memory area VMA, it could exploit a time-of-check to time-of-use TOCTOU vulnerability. This allows the process to alter the offsets array during a transaction before it is...
