OESA-2022-1677 (CVE-2022-1205)

Vulnerability from osv_openeuler – Published: 2022-05-28 11:04 – Updated: 2026-08-06 11:04 – Source website

Summary

kernel security update

Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

A NULL pointer dereference flaw was found in the Linux kernel’s Amateur Radio AX.25 protocol functionality in the way a user connects with the protocol. This flaw allows a local user to crash the system.(CVE-2022-1205)

UAF causes the system to crash Exploit conditions: The root user reduces the reference count of drm_vgem_gem_object through ioctl$DRM_IOCTL_MODE_DESTROY_DUMB, and vgem_gem_dumb_create will access the released drm_vgem_gem_object Technical reason: The gpu driver can reduce the reference count of drm_vgem_gem_object through ioctl Concurrency causes uaf judgment method: CONFIG_DRM is not configured No circumvention measures are involved: none(CVE-2022-1419)

A concurrency use-after-free issue was discovered between reset_interrupt and floppy_end_request in the latest kernel version (5.17.5 for now). The root cause is that after deallocating current_req in floppy_end_request, reset_interrupt still holds the freed current_req->error_count and accesses it concurrently.(CVE-2022-1652)

Severity

7.0 (High)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
