CVE-2023-53705

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel’s IPv6 functionality within the ipv6 find tlv() function. The issue involves accessing data out of bounds due to insufficient checks on the length of data to be parsed. Specifically, the optlen variable is retrieved without verifying if more than one byte needs parsing, potentially leading to an out-of-bounds access. This was discovered by InfoTeCS on behalf of Linux Verification Center using SVACE.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
