FKIE_CVE-2024-35823

Vulnerability from fkie_nvd - Published: 2024-05-17 14:15 - Updated: 2026-06-17 07:35
Severity
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Summary
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.
