drm/msm/gem: fix error handling in msm_ioctl_gem_info_get_metadata()

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 47cbfe2608314b833ad61a65827d8fb363bc2d2d, 697e1a9559f6962f999cc4c748c2ffffcc0a7a7a, b079e85c91f446f29e808d8291189e897f1884ff.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 47cbfe2608314b833ad61a65827d8fb363bc2d2d, 697e1a9559f6962f999cc4c748c2ffffcc0a7a7a, b079e85c91f446f29e808d8291189e897f1884ff or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/msm/gem: fix error handling in msm_ioctl_gem_info_get_metadata() msm_ioctl_gem_info_get_metadata() always returns 0 regardless of errors. When copy_to_user() fails or the user buffer is too small, the error code stored in ret is ignored because the function unconditionally returns 0. This causes userspace to believe the ioctl succeeded when it did not. Additionally, kmemdup() can return NULL on allocation failure, but the return value is not checked. This leads to a NULL pointer dereference in the subsequent copy_to_user() call. Add the missing NULL check for kmemdup() and return ret instead of 0. Note that the SET counterpart (msm_ioctl_gem_info_set_metadata) correctly returns ret. Patchwork: https://patchwork.freedesktop.org/patch/714478/
