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/","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-476"],"references":["https://git.kernel.org/stable/c/293f53263266bc4340d777268ab4328a97f041fa","https://git.kernel.org/stable/c/42cf045086feae77b212f0f66e742b91a5b566b7","https://git.kernel.org/stable/c/563aa81fd66a4e7e6e551a0e02bcc23957cafe2f","https://git.kernel.org/stable/c/e8e9f2a12a6214080c8ea83220a596f6e1dedc6c","https://git.kernel.org/stable/c/f7ad916273483748582d97cfa31054ccb19224f3"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:57:07.693694550+00:00"},"epss":{"cve":"CVE-2024-50156","score":0.00216,"percentile":0.12072,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
