selinux: fix double free of cond_list on error paths

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.24% (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 186edf7e368c40d06cf727a1ad14698ea67b74ad, 70caa32e6d81f45f0702070c0e4dfe945e92fbd7, 7ed9cbf7ac0d4ed86b356e1b944304ae9ee450d4.

Low priority for now. Upgrade to Linux Linux 186edf7e368c40d06cf727a1ad14698ea67b74ad, 70caa32e6d81f45f0702070c0e4dfe945e92fbd7, 7ed9cbf7ac0d4ed86b356e1b944304ae9ee450d4 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

In the Linux kernel, the following vulnerability has been resolved: selinux: fix double free of cond_list on error paths On error path from cond_read_list() and duplicate_policydb_cond_list() the cond_list_destroy() gets called a second time in caller functions, resulting in NULL pointer deref. Fix this by resetting the cond_list_len to 0 in cond_list_destroy(), making subsequent calls a noop. Also consistently reset the cond_list pointer to NULL after freeing.
