{"id":"CVE-2024-49909","summary":"drm/amd/display: Add NULL check for function pointer in dcn32_set_output_transfer_func","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Add NULL check for function pointer in dcn32_set_output_transfer_func\n\nThis commit adds a null check for the set_output_gamma function pointer\nin the dcn32_set_output_transfer_func function. Previously,\nset_output_gamma was being checked for null, but then it was being\ndereferenced without any null check. This could lead to a null pointer\ndereference if set_output_gamma is null.\n\nTo fix this, we now ensure that set_output_gamma is not null before\ndereferencing it. We do this by adding a null check for set_output_gamma\nbefore the call to set_output_gamma.","modified":"2026-05-07T04:17:58.463571Z","published":"2024-10-21T18:01:38.803Z","related":["SUSE-SU-2024:3983-1","SUSE-SU-2024:3984-1","SUSE-SU-2024:3985-1","SUSE-SU-2024:4314-1","SUSE-SU-2024:4318-1","SUSE-SU-2024:4364-1","SUSE-SU-2024:4387-1","SUSE-SU-2025:20163-1","SUSE-SU-2025:20164-1","SUSE-SU-2025:20246-1","SUSE-SU-2025:20247-1","USN-7276-1","USN-7277-1","openSUSE-SU-2024:14500-1","openSUSE-SU-2025:14705-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/49xxx/CVE-2024-49909.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/28574b08c70e56d34d6f6379326a860b96749051"},{"type":"WEB","url":"https://git.kernel.org/stable/c/496486950c3d2aebf46a3be300296ac091da7a2d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5298270bdabe97be5b8236e544c9e936415fe1f2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e087c9738ee1cdeebde346f4dfc819e5f7057e90"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f38b09ba6a335c511eb27920bb9bb4a1b2c20084"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/49xxx/CVE-2024-49909.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-49909"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"235c67634230b0f9ad8c0185272fed36c892b1c4"},{"fixed":"e087c9738ee1cdeebde346f4dfc819e5f7057e90"},{"fixed":"f38b09ba6a335c511eb27920bb9bb4a1b2c20084"},{"fixed":"496486950c3d2aebf46a3be300296ac091da7a2d"},{"fixed":"5298270bdabe97be5b8236e544c9e936415fe1f2"},{"fixed":"28574b08c70e56d34d6f6379326a860b96749051"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-49909.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"6.1.120"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.64"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.10.14"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.11.0"},{"fixed":"6.11.3"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-49909.json"}}],"schema_version":"1.7.5"}
