Linux Kernel Vulnerability in F2FS Product by The Linux Foundation

CVE-2023-53301

What is CVE-2023-53301?

The Linux kernel has addressed a NULL pointer dereference issue within the F2FS filesystem. This flaw can cause kernel crashes under specific conditions when the 'io->bio' pointer is null during write operations. The error occurs when the system fails to check for a null value before proceeding, potentially leading to a system panic. Proper validation of pointers is crucial to maintain stability and reliability in the filesystem's operation.
