Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel up to 5.10.222/5.15.163/6.1.100/6.6.41/6.9.10. Affected is some unknown functionality of the component null_blk. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: null_blk: fix validation of block size Block size should be between 512 and PAGE_SIZE and be a power of 2. The current check does not validate this, so update the check. Without this patch, null_blk would Oops due to a null pointer deref when loaded with bs=1536 [1]. [axboe: remove unnecessary braces and != 0 check]

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2024-41077 since 07/12/2024. The exploitability is told to be difficult. The technical details are unknown and an exploit is not available.
