What is CVE-2025-38243?

The Linux kernel's btrfs implementation is susceptible to an invalid memory access issue during log replay due to improper handling of inode pointers. When the function read_one_inode() retrieves a NULL pointer, it can lead to erroneous behavior where an invalid inode pointer is dereferenced. This flaw can cause system crashes, making it critical for users and administrators to ensure their systems are patched against this vulnerability to maintain stability and security.
