https://notcve.org/view.php?id=CVE-2024-47720
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check for set_output_gamma in dcn30_set_output_transfer_func This commit adds a null check for the set_output_gamma function pointer in the dcn30_set_output_transfer_func function. Previously, set_output_gamma was being checked for nullity at line 386, but then it was being dereferenced without any nullity check at line 401. This could potentially lead to a null pointer dereference error if set_output_gamma is indeed null. To fix this, we now ensure that set_output_gamma is not null before dereferencing it. We do this by adding a nullity check for set_output_gamma before the call to set_output_gamma at line 401. If set_output_gamma is null, we log an error message and do not call the function. This fix prevents a potential null pointer dereference error. drivers/gpu/drm/amd/amdgpu/.. • https://git.kernel.org/stable/c/d99f13878d6f9c286b13860d8bf0b4db9ffb189a https://git.kernel.org/stable/c/44948d3cb943602ba4a0b5ed3c91ae0525838fb1 https://git.kernel.org/stable/c/64886a4e6f1dce843c0889505cf0673b5211e16a https://git.kernel.org/stable/c/ddf9ff244d704e1903533f7be377615ed34b83e7 https://git.kernel.org/stable/c/84edd5a3f5fa6aafa4afcaf9f101f46426c620c9 https://git.kernel.org/stable/c/72ee32d0907364104fbcf4f68dd5ae63cd8eae9e https://git.kernel.org/stable/c/08ae395ea22fb3d9b318c8bde28c0dfd2f5fa4d2 •
