Summary

kernel security update

Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

In (TBD) of (TBD), there is a possible way to corrupt kernel memory due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-220738351References: Upstream kernel(CVE-2022-20568)

In verity_target of dm-verity-target.c, there is a possible way to modify read-only files due to a missing permission check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-234475629References: Upstream kernel(CVE-2022-20572)

In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused by refcount races, affecting dvb_demux_open and dvb_dmxdev_release.(CVE-2022-41218)

An issue was discovered in the Linux kernel through 5.16-rc6. malidp_crtc_reset in drivers/gpu/drm/arm/malidp_crtc.c lacks check of the return value of kzalloc() and will cause the null pointer dereference.(CVE-2022-3115)

An issue was discovered in the Linux kernel through 5.16-rc6. free_charger_irq() in drivers/power/supply/wm8350_power.c lacks free of WM8350_IRQ_CHG_FAST_RDY, which is registered in wm8350_init_charger().(CVE-2022-3111)

An issue was discovered in the Linux kernel through 5.16-rc6. kfd_parse_subtype_iolink in drivers/gpu/drm/amd/amdkfd/kfd_crat.c lacks check of the return value of kmemdup().(CVE-2022-3108)

Severity

7.8 (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.
