Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the active flag for FTEs in the net/mlx5 component not being checked by locking during deletion, causing the...

The vulnerability of the filemap_fault_recheck_pte_none() function in the Linux kernel’s memory management subsystem allows an attacker to compromise the integrity of protected information.

The vulnerability of the filemapfaultrecheckptenone function in the mm/filemap.c module of the Linux kernel’s memory management subsystem is related to the repeated use of previously freed memory due to competitive access to resources race condition. Exploiting this vulnerability could allow an...

kernel: x86/mm/pat: fix VM_PAT handling in COW mappings

CVE-2024-35877 pertains to a flaw in the Linux kernel's handling of Page Attribute Table PAT settings during Copy-On-Write COW operations. When a write operation triggers a COW event, the kernel may replace the original page table entries PTEs with anonymous folios. This replacement disrupts the...
