CVE-2024-47745

CVE-2024-47745 is a vulnerability in the Linux kernel that allows a local attacker to bypass the W^X (Write XOR Execute) policy, specifically when enforced by SELinux. This occurs because the remap_file_pages syscall handler directly calls do_mmap() without the necessary security_mmap_file() LSM hook, enabling remapping of pages to RWX (Read-Write-Execute) if personality(READ_IMPLIES_EXEC) was previously set. With a CVSS score of 7.8 (HIGH), this vulnerability could lead to high confidentiality, integrity, and availability impacts. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
