UBUNTU-CVE-2024-35877

In the Linux kernel, the following vulnerability has been resolved: x86/mm/pat: fix VMPAT handling in COW mappings PAT handling won't do the right thing in COW mappings: the first PTE or, in fact, all PTEs can be replaced during write faults to point at anon folios. Reliably recovering the correc...

CVE-2024-35872

Summary: CVE-2024-35872 affects the Linux kernel mm/secretmem feature. The issue arose because folios for secretmem could be added to batches without the LRU flag, making folio_is_secretmem() unreliable and enabling a local attacker to trigger GUP-fast on secretmem folios. The fix removes the unr...
