CVE-2023-53681

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel’s bcache subsystem related to memory allocation. Specifically, the bch btree node alloc function could return a NULL pointer under certain conditions. This could lead to a NULL pointer dereference in calling functions such as btree split and subsequently bch btree node alloc. The issue has been addressed by initializing the return value within the bch btree node alloc function to ensure consistent failure behavior.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
