Upgrade RHEL:8 kernel-modules to version 0:4.18.0-553.16.1.el8_10 or higher.
This issue was patched in RHSA-2024:5101.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-modules package and not the kernel-modules package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
vt: fix unicode buffer corruption when deleting characters
This is the same issue that was fixed for the VGA text buffer in commit 39cdb68c64d8 ("vt: fix memory overlapping when deleting chars in the buffer"). The cure is also the same i.e. replace memcpy() with memmove() due to the overlaping buffers.
