CVE-2021-47491

In the Linux kernel, the following vulnerability has been resolved: mm: khugepaged: skip huge page collapse for special files The read-only THP for filesystems will collapse THP for files opened readonly and mapped with VMEXEC. The intended usecase is to avoid TLB misses for large text segments...

CVE-2021-47491

CVE-2021-47491 concerns the Linux kernel vulnerability in mm: khugepaged, where read-only THP for filesystems could collapse THP for readonly/executable mappings of non-regular files (e.g., block devices). The root cause is that THP collapse was allowed for such files due to an insufficient vm_fi...
