K000151739: Linux kernel vulnerability CVE-2024-47745

Security Advisory Description In the Linux kernel, the following vulnerability has been resolved: mm: call the securitymmapfile LSM hook in remapfilepages The remapfilepages syscall handler calls dommap directly, which doesn't contain the LSM security check. And if the process has called...

kernel: mm: call the security_mmap_file() LSM hook in remap_file_pages()

A flaw was found in the remapfilepages function in mm/mmap.c in the Linux kernel, where it does not properly restrict execute access. This vulnerability allows local users to bypass intended SELinux W^X policy restrictions...

CVE-2024-47745

The CVE-2024-47745 entry describes a Linux kernel vulnerability where remap_file_pages bypassed W^X enforcement when using personality(READ_IMPLIES_EXEC) followed by a RW remap, due to the remap_file_pages path calling do_mmap() before the LSM security check. A fix adds a security_mmap_file LSM h...
