CVE-2022-50284: ipc: fix memory leak in init_mqueue_fs()
In the Linux kernel, the following vulnerability has been resolved:
ipc: fix memory leak in init_mqueue_fs()
When setup_mq_sysctls() failed in init_mqueue_fs(), mqueue_inode_cachep is
not released. In order to fix this issue, the release path is reordered.
Security readout for executives and security teams
Plain-English summary
This CVE is a Linux kernel memory leak in POSIX message queue filesystem initialization. If a setup step fails, kernel memory allocated for the message queue inode cache may not be released. The source does not provide CVSS, active exploitation evidence, or a business-impact chain.
Executive priority
Set this to normal patch-cycle priority unless your Linux vendor assigns higher severity. There is no source-backed evidence of active exploitation, but kernel memory leaks still matter for platform reliability and should not be ignored.
Technical view
init_mqueue_fs() can leak mqueue_inode_cachep when setup_mq_sysctls() fails. The resolved kernel change reorders the release path so allocated cache state is cleaned up on failure. Public sources identify Linux kernel versions and stable commits, but do not describe exploitability beyond the leak.
Likely exposure
Exposure appears limited to systems running affected Linux kernel builds listed by the CVE source. The source lists 5.19, 6.0.16, 6.1.2, 6.2, and an ambiguous 0 entry; validate against your distribution’s kernel advisories.
Exploitation context
The provided sources do not show active exploitation, public weaponization, or inclusion in CISA KEV. Treat this as a kernel reliability and resource-management issue unless vendor guidance adds stronger impact evidence.
Researcher notes
The public record is sparse: no CVSS, CWE, exploit status, or detailed attacker preconditions are provided. Analysis should focus on kernel version mapping, distro backports, and whether local vendor kernels include the stable cleanup-path fix.
Mitigation direction
Check Linux distribution advisories for CVE-2022-50284 coverage.
Update affected kernels through the supported vendor channel.
Confirm the deployed kernel includes one of the referenced stable fixes.
Prioritize internet-facing or multi-tenant Linux hosts if vendor severity increases.
Validation and detection
Inventory running kernel versions across Linux assets.
Compare versions against vendor advisories and the CVE affected data.
Verify patched kernels include the referenced stable commit lineage.
Monitor CVE and vendor pages for severity or exploit-status updates.
