PT-2026-36420

In the Linux kernel, the following vulnerability has been resolved: drm/xe/xe pagefault: Disallow writes to read-only VMAs The page fault handler should reject write/atomic access to read only VMAs. Add code to handle this in xe pagefault service after the VMA lookup. v2: - Apply max line length...

CVE-2026-31787 xen/privcmd: fix double free via VMA splitting

In the Linux kernel, the following vulnerability has been resolved: xen/privcmd: fix double free via VMA splitting privcmdvmops defines .close privcmdclose, but neither .maysplit nor .open. When userspace does a partial munmap on a privcmd mapping, the kernel splits the VMA via splitvma. Since...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the VMA segmentation in the xen privcmd driver, leading to double deallocation and potentially...

CVE-2026-31654

A flaw was found in the Linux kernel. When a shared memory mapping is created for /dev/zero, a memory leak can occur if the virtual memory area VMA allocation fails. This happens because a newly allocated file, intended to back the mapping, is not properly released in the error path, leading to...

CVE-2026-31602

The CVE-2026-31602 issue affects the Linux kernel ALSA ctxfi driver, where ct_vm_map() may access memory beyond allocated space when CT_PTP_NUM exceeds 1 (AMD64), causing a page fault and potential system crash. The root cause is that ct_vm_map() always uses PTEs in vm->ptp[0].area regardless ...

CVE-2026-31597

The CVE-2026-31597 vulnerability affects the Linux kernel OCFS2 code. A use-after-free occurs in ocfs2_fault() when VM_FAULT_RETRY triggers after filemap_fault() drops mmap_lock, allowing a concurrent munmap() to free the vm_area_struct and causing ocfs2_fault() to dereference a dangling vma. The...
