Description
In the Linux kernel, the following vulnerability has been resolved: crypto: ccree - fix a memory leak in cc_mac_digest() Add cc_unmap_result() if cc_map_hash_request_final() fails to prevent potential memory leak.
A memory leak vulnerability has been identified in the Linux kernel's crypto subsystem, specifically within the CCREE driver handling hash functions. This issue arises in the 'cc_mac_digest' function, where a failure in finalizing a hash request can lead to unreturned memory. The vulnerability is present in the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree, where this vulnerability has been addressed. Instructions for downloading the patched version are available on the Linux kernel official website.
