kernel: selinux: fix overlayfs mmap() and mprotect() access checks

A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...

CVE-2026-74646

CVE-2026-74646 is a race condition in the Linux kernel's misc: fastrpc subsystem. When a fastrpc invoke is interrupted by a signal, fastrpc_internal_invoke() moves all buffers from fl->mmaps onto cctx->invoke_interrupted_mmaps via list_del()/list_add_tail() without holding fl->lock , the...

CVE-2026-74641

CVE-2026-74641 is a local privilege escalation / DoS flaw in the Linux kernel ALSA usx2y driver . The function snd_us428ctls_vm_fault() converts a page-fault offset into a kernel address without bounds-checking it against the single-page us428ctls_sharedmem region. Because file_mmap_size_max() re...

CVE-2026-74599

CVE-2026-74599 is a race condition in the Linux kernel 's mm/ptdump subsystem. Previous fixes established that kernel page table freeing occurs while holding an mmap read lock on init_mm , but x86 and arm64 architectures can perform a ptdump over a non-init_mm via ptdump_walk_pgd(). Since kernel ...
