CVE-2026-53015 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug-core package and not the kernel-rt-debug-core package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
erofs: unify lcn as u64 for 32-bit platforms
As sashiko reported [1], lcn was typed as unsigned long (or
unsigned int sometimes), which is only 32 bits wide on 32-bit
platforms, which causes (lcn << lclusterbits) to be truncated
at 4 GiB.
In order to consolidate the logic, just use u64 consistently
around the codebase.
