NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-devel-rt package and not the kernel-devel-rt package as distributed by SLES.

An issue was discovered in the Linux kernel 4.4 through 5.7.1. drivers/tty/vt/keyboard.c has an integer overflow if k_ascii is called several times in a row, aka CID-b86dab054059. NOTE: Members in the community argue that the integer overflow does not lead to a security issue in this case.
