A set of 5 medium-severity security flaws in Arm’s Mali GPU driver has ongoing to remain unpatched on Android equipment for months, inspite of fixes released by the chipmaker.
Google Project Zero, which found and noted the bugs, claimed Arm tackled the shortcomings in July and August 2022.
“These fixes have not however designed it downstream to influenced Android devices (such as Pixel, Samsung, Xiaomi, Oppo, and some others),” Task Zero researcher Ian Beer mentioned in a report. “Gadgets with a Mali GPU are at the moment vulnerable.”
The vulnerabilities, collectively tracked underneath the identifiers CVE-2022-33917 (CVSS score: 5.5) and CVE-2022-36449 (CVSS score: 6.5), issue a circumstance of inappropriate memory processing, thus allowing a non-privileged consumer to achieve access to freed memory.
The 2nd flaw, CVE-2022-36449, can be even more weaponized to generate outside of buffer bounds and disclose specifics of memory mappings, in accordance to an advisory issued by Arm. The checklist of afflicted motorists is beneath –
CVE-2022-33917
- Valhall GPU Kernel Driver: All variations from r29p0 – r38p0
CVE-2022-36449
- Midgard GPU Kernel Driver: All versions from r4p0 – r32p0
- Bifrost GPU Kernel Driver: All versions from r0p0 – r38p0, and r39p0
- Valhall GPU Kernel Driver: All variations from r19p0 – r38p0, and r39p0
The conclusions the moment once more spotlight how patch gaps can render millions of devices susceptible at the moment and place them at risk of heightened exploitation by threat actors.
“Just as users are advisable to patch as swiftly as they can the moment a release containing security updates is readily available, so the exact same applies to vendors and businesses,” Beer mentioned.
