Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a memory overlapping copy in the Linux kernel's vt component when deleting characters in the buffer. This can cause data corruption when
scr memcpyw is optimized to memcpy because memcpy does not ensure its behavior if the destination buffer overlaps with the source buffer. The line buffer is not always broken due to the use of hardware acceleration, whose result is not deterministic.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
