CVE-2024-47720

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.58

Description A null pointer dereference error could occur in the Linux kernel due to a missing null check for the set output gamma function pointer in the dcn30 set output transfer func function. This issue has been resolved by adding a nullity check for set output gamma before dereferencing it. If set output gamma is null, an error message is logged and the function is not called. The fix prevents a potential null pointer dereference error.

Recommendations To resolve this issue, update the Linux kernel to version 6.6.58 or later. As a temporary workaround, consider adding a nullity check for set output gamma before calling it in the dcn30 set output transfer func function.
