Summary
A memory leak in the Linux kernel's blk_revalidate_disk_zones() function occurs on zone revalidation error paths. When disk_revalidate_zone_resources() successfully allocates args.zones_cond but subsequent validation fails, the memory is not freed.
Risk Assessment
This memory leak can gradually exhaust system resources, potentially causing system instability or crashes in environments heavily using zoned block devices.
Recommendation
Immediately update the Linux kernel to a version containing the fix that addresses the memory leak. Monitor your distribution for the availability of the patch.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: block: fix zones_cond memory leak on zone revalidation error paths When blk_revalidate_disk_zones() fails after disk_revalidate_zone_resources() has allocated args.zones_cond, the memory is leaked because no error path frees it.
