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/"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/msm/disp/msm_disp_snapshot_util.c"],"versions":[{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"42cf045086feae77b212f0f66e742b91a5b566b7","status":"affected","versionType":"git"},{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"e8e9f2a12a6214080c8ea83220a596f6e1dedc6c","status":"affected","versionType":"git"},{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"f7ad916273483748582d97cfa31054ccb19224f3","status":"affected","versionType":"git"},{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"563aa81fd66a4e7e6e551a0e02bcc23957cafe2f","status":"affected","versionType":"git"},{"version":"98659487b845c05b6bed85d881713545db674c7c","lessThan":"293f53263266bc4340d777268ab4328a97f041fa","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/msm/disp/msm_disp_snapshot_util.c"],"versions":[{"version":"5.14","status":"affected"},{"version":"0","lessThan":"5.14","status":"unaffected","versionType":"semver"},{"version":"5.15.170","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.115","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.59","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.11.6","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"5.15.170"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.1.115"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.6.59"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.11.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/42cf045086feae77b212f0f66e742b91a5b566b7"},{"url":"https://git.kernel.org/stable/c/e8e9f2a12a6214080c8ea83220a596f6e1dedc6c"},{"url":"https://git.kernel.org/stable/c/f7ad916273483748582d97cfa31054ccb19224f3"},{"url":"https://git.kernel.org/stable/c/563aa81fd66a4e7e6e551a0e02bcc23957cafe2f"},{"url":"https://git.kernel.org/stable/c/293f53263266bc4340d777268ab4328a97f041fa"}],"title":"drm/msm: Avoid NULL dereference in msm_disp_state_print_regs()","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.5,"attackVector":"LOCAL","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"id":"CVE-2024-50156","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2025-10-01T20:20:34.229291Z"}}}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-476","description":"CWE-476 NULL Pointer Dereference"}]}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-10-01T20:27:12.781Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T22:26:16.199Z"}}]}}
