{"id":"AZL-55294","summary":"CVE-2024-53201 affecting package kernel 6.6.126.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Fix null check for pipe_ctx-\u003eplane_state in dcn20_program_pipe\n\nThis commit addresses a null pointer dereference issue in\ndcn20_program_pipe(). Previously, commit 8e4ed3cf1642 (\"drm/amd/display:\nAdd null check for pipe_ctx-\u003eplane_state in dcn20_program_pipe\")\npartially fixed the null pointer dereference issue. However, in\ndcn20_update_dchubp_dpp(), the variable pipe_ctx is passed in, and\nplane_state is accessed again through pipe_ctx. Multiple if statements\ndirectly call attributes of plane_state, leading to potential null\npointer dereference issues. This patch adds necessary null checks to\nensure stability.","modified":"2026-04-01T05:18:34.493589Z","published":"2024-12-27T14:15:27Z","upstream":["CVE-2024-53201"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53201"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.126.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-55294.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"}]}
