CVE-2022-50211:
Linux Kernel vulnerability analysis and mitigation
Overview
In the Linux kernel, a KASAN (Kernel Address Sanitizer) warning was discovered in raid10_remove_disk function when running the lvm test lvconvert-raid-reshape.sh. The vulnerability was identified and disclosed in June 2025 (NVD).
Technical details
The vulnerability manifests as a slab-out-of-bounds read of size 8 at a specific memory address. The issue occurs in the raid10_remove_disk function when the value 'number' is not properly validated before use. The bug was detected during the execution of the lvm test lvconvert-raid-reshape.sh and triggers a KASAN warning (NVD).
Impact
The vulnerability could potentially lead to a read of memory outside the allocated bounds in the Linux kernel's RAID10 implementation, which may result in information disclosure or system stability issues (NVD).
Mitigation and workarounds
The vulnerability has been resolved by adding proper validation of the 'number' value before its use in the raid10_remove_disk function. This fix ensures that the value is valid before performing memory operations (NVD).
