CVE-2024-42250 (GCVE-0-2024-42250)

Vulnerability from cvelistv5 – Published: 2024-08-07 15:14 – Updated: 2025-11-03 22:02
VLAI?
Summary
In the Linux kernel, the following vulnerability has been resolved: cachefiles: add missing lock protection when polling Add missing lock protection in poll routine when iterating xarray, otherwise: Even with RCU read lock held, only the slot of the radix tree is ensured to be pinned there, while the data structure (e.g. struct cachefiles_req) stored in the slot has no such guarantee. The poll routine will iterate the radix tree and dereference cachefiles_req accordingly. Thus RCU read lock is not adequate in this case and spinlock is needed here.
Severity ?
