CVE-2024-42233

In the Linux kernel, a vulnerability was fixed by replacing pteoffsetmap with pteoffsetmapnolock in the filemapfaultrecheckptenone function. The original use of pteoffsetmap relied on a potentially stale page table lock PTL, which could lead to a use-after-free UAF condition if the page table was...
