This occurs when the oom reaper a kernel mechanism that attemp...
DEBIAN-CVE-2026-90303
In the Linux kernel, the following vulnerability has been resolved: ARM: 9485/1: mm: acquire mmap write lock around showpte for user faults When CONFIGDEBUGUSER=y, and cmdline "userdebug=31" is set, a user fault may trigger showpte without any lock. If another thread in the same process...
PT-2026-94690
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A deadlock occurs in the BPF subsystem when the arena vm fault function fails to acquire the arena-spinlock. The function returns VM FAULT RETRY, which triggers the do user addr fault pa...
Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1
In the Linux kernel, the following vulnerability has been resolved: Binder: Fix for use-after-free in shinker’s callback The mmap read lock is used during shinker’s callback, which means that using the alloc-vma pointer is not safe, as it could lead to a race condition with munmap. As of commit...

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 ...
