OESA-2022-1794 (CVE-2022-2380)
Vulnerability from osv_openeuler – Published: 2022-07-30 11:05 – Updated: 2026-08-06 11:05 – Source websiteThe Linux Kernel, the operating system core itself.
Security Fix(es):
The Linux kernel was found vulnerable out of bounds memory access in the drivers/video/fbdev/sm712fb.c:smtcfb_read() function. The vulnerability could result in local attackers being able to crash the kernel.(CVE-2022-2380)
In USB driver, there is a possible out of bounds read due to a heap buffer overflow. This could lead to local information disclosure with User execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-216825460References: Upstream kernel(CVE-2022-20227)
Kernel lockdown bypass when UEFI secure boot is disabled / unavailable and IMA appraisal is enabled.(CVE-2022-21505)
