CVE-2026-53127 Details
Description
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.
A memory leak vulnerability has been identified in the Linux kernel's block layer, specifically within the zone revalidation process. When the function 'blk_revalidate_disk_zones()' fails after 'disk_revalidate_zone_resources()' has allocated memory for zone conditions, the allocated memory is not freed, leading to a leak. This issue arises in the stable version of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched version are available on the official Linux kernel website.
