CVE-2024-41935 Details
Description
In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to shrink read extent node in batches We use rwlock to protect core structure data of extent tree during its shrink, however, if there is a huge number of extent nodes in extent tree, during shrink of extent tree, it may hold rwlock for a very long time, which may trigger kernel hang issue. This patch fixes to shrink read extent node in batches, so that, critical region of the rwlock can be shrunk to avoid its extreme long time hold.
A vulnerability in the Linux kernel's F2FS file system has been addressed. The issue involved the improper management of read extent nodes during the shrinking process of the extent tree. The original implementation used a read-write lock to protect the core data, but in cases with a large number of extent nodes, this could lead to prolonged lock holds, causing potential kernel hang issues. The vulnerability has been resolved by modifying the shrink process to handle read extent nodes in batches, reducing the lock's critical region hold time.
