{"id":"AZL-51042","summary":"CVE-2024-49911 affecting package kernel for versions less than 6.6.64.2-9","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Add NULL check for function pointer in dcn20_set_output_transfer_func\n\nThis commit adds a null check for the set_output_gamma function pointer\nin the dcn20_set_output_transfer_func function. Previously,\nset_output_gamma was being checked for null at line 1030, but then it\nwas being dereferenced without any null check at line 1048. This could\npotentially lead to a null pointer dereference error if set_output_gamma\nis 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 at line 1048.","modified":"2026-04-01T05:17:39.382768Z","published":"2024-10-21T18:15:13Z","upstream":["CVE-2024-49911"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-49911"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.64.2-9"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-51042.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
