It will re-allocate the pointer it is\npassed on first call, when the data is ascii85 encoded, using kvmalloc/\nkvfree().  Which means the data *passed* to it must be kvmalloc'd, ie.\nwe cannot use the state_kcalloc() helper.\n\nThis partially reverts commit ec8f1813bf8d (\"drm/msm/a6xx: Replace\nkcalloc() with kvzalloc()\"), but adds the missing kvfree() to fix the\nmemory leak that was present previously.  And adds a warning comment.\n\nPatchwork: https://patchwork.freedesktop.org/patch/507014/","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/4b1bbc0571a5d7ee10f754186dc3d619b9ced5c1","https://git.kernel.org/stable/c/83d18e9d9c0150d98dc24e3642ea93f5e245322c"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:18:08.089039631+00:00"},"epss":{"cve":"CVE-2022-50867","score":0.00145,"percentile":0.03733,"date":"2026-10-31"},"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).
