OESA-2022-1942 (CVE-2022-26373)

Vulnerability from osv_openeuler – Published: 2022-09-23 11:05 – Updated: 2026-08-06 11:05 – Source website

Summary

kernel security update

Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.(CVE-2022-26373)

A heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged code on the target system to exploit this vulnerability.(CVE-2022-2991)

An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data.(CVE-2022-2905)

An issue was discovered in the Linux kernel through 5.16-rc6. There is a lack of check after calling vzalloc() and lack of free after allocation in drivers/media/test-drivers/vidtv/vidtv_s302m.c.(CVE-2022-3078)

An issue was discovered in the Linux kernel through 5.19.8. drivers/firmware/efi/capsule-loader.c has a race condition with a resultant use-after-free.(CVE-2022-40307)

Severity

6.7 (Medium)

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.
