{"id":"AZL-53268","summary":"CVE-2024-50156 affecting package kernel for versions less than 5.15.173.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/msm: Avoid NULL dereference in msm_disp_state_print_regs()\n\nIf the allocation in msm_disp_state_dump_regs() failed then\n`block-\u003estate` can be NULL. The msm_disp_state_print_regs() function\n_does_ have code to try to handle it with:\n\n  if (*reg)\n    dump_addr = *reg;\n\n...but since \"dump_addr\" is initialized to NULL the above is actually\na noop. The code then goes on to dereference `dump_addr`.\n\nMake the function print \"Registers not stored\" when it sees a NULL to\nsolve this. Since we're touching the code, fix\nmsm_disp_state_print_regs() not to pointlessly take a double-pointer\nand properly mark the pointer as `const`.\n\nPatchwork: https://patchwork.freedesktop.org/patch/619657/","modified":"2026-04-01T05:18:00.165539Z","published":"2024-11-07T10:15:07Z","upstream":["CVE-2024-50156"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-50156"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.15.173.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-53268.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"}]}
