Jan 2, 2024KernelSU is a Kernel-based root solution for Android devices.CVE-2023-49794 · Other software · tiann · reported by GitHubMedium 6.7
KernelSU is a Kernel-based root solution for Android devices. In versions 0.7.1 and prior, the logic of get apk path in KernelSU kernel module can be bypassed, which causes any malicious apk named `me.weishu.kernelsu` get root permission. If a KernelSU module installed device try to install any not checked apk which package name equal to the official KernelSU Manager, it can take over root privileges on the device. As of time of publication, a patched version is not available.

Oct 30, 2023KernelSU is a Kernel based root solution for Android.CVE-2023-46139 · Other software · tiann · reported by GitHubMedium 5
KernelSU is a Kernel based root solution for Android. Starting in version 0.6.1 and prior to version 0.7.0, if a KernelSU installed device is infected with a malware whose app signing block specially constructed, it can take over root privileges on the device. The vulnerable verification logic actually obtains the signature of the last block with an id of `0x7109871a`, while the verification logic during Android installation is to obtain the first one. In addition to the actual signature upgrade that has been fixed (KSU thought it was V2 but was actually V3), there is also the problem of actual signature downgrading (KSU thought it was V2 but was actually V1). Find a condition in the signature verification logic that will cause the signature not to be found error, and KernelSU does not implement the same conditions, so KSU thinks there is a V2 signature, but the APK signature verification actually uses the V1 signature. This issue is fixed in version 0.7.0. As workarounds, keep the KernelSU manager installed and avoid installing unknown apps.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
