CVE-2024-56608
CVSS v3.1
7.8
High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.8.0
Description
An issue was identified in the
dcn21 link encoder create function where an out-of-bounds access could occur when the hpd source index was used to reference the link enc hpd regs array. This array has a fixed size and the index was not being checked against the array's bounds before accessing it. The fix adds a conditional check to ensure that the hpd source index is within the valid range of the link enc hpd regs array. If the index is out of bounds, the function now returns NULL to prevent undefined behavior.Recommendations
As a temporary workaround, consider disabling the
dcn21 link encoder create function until a patch is available. Update the Linux kernel to a version that includes the fix for this issue.Exploit
