How to fix?

There is no fixed version for RHEL:10 kernel-rt-64k-debug-modules-extra.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-64k-debug-modules-extra package and not the kernel-rt-64k-debug-modules-extra package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

btrfs: protect sb_write_pointer() with invalidate lock

sb_write_pointer() reads the super block from the block device page cache using read_cache_page_gfp(). This has the same race with BLKBSZSET as the one fixed by commit 3f29d661e568 ("btrfs: sync read disk super and set block size").

Take the mapping invalidate lock around read_cache_page_gfp() to serialize the read against block size changes.
