CVE-2023-26083

CVE-2023-26083 —— 通过时间线流泄漏 Mali GPU 内核地址 本仓库包含针对 CVE-2023-26083 的概念验证（PoC）漏洞利用代码。该漏洞位于 Mali GPU 驱动程序（Arm Mali GPU Kernel Driver）中，允许非特权用户通过时间线流（/dev/mali0）泄漏内核指针和敏感的内部信息。 漏洞概述 Mali GPU 驱动程序提供了一条“时间线流”（tlstream）功能，用于性能分析和调试。该流导出的事件包含原始内核指针（例如...

CVE-2026-80810

A flaw was found in the Linux kernel. An integer overflow vulnerability in the iouring/rsrc component, specifically within the iovecfillbvec function, can lead to incorrect memory calculations when handling very large memory pages. This error causes the kernel to access memory outside of its...

CVE-2026-80887

A flaw was found in the drm/vmwgfx component of the Linux kernel. An integer overflow vulnerability exists in the vmwshaderdefine function due to improper validation of user-supplied shader window size and offset. When the offset value is close to its maximum, an unsigned addition can wrap around...

CVE-2026-80852

A flaw was found in the Linux kernel's TLS device driver. A local attacker could exploit an out-of-bounds write vulnerability in the tlsappendfrag function when handling TLSTXZEROCOPYRO with spliceSPLICEFMORE operations. This flaw allows an attacker to cause memory corruption, leading to a denial...

CVE-2019-2215

Bad-Binder CVE-2019-2215 以下是针对 bad binder CVE-2019-2215 漏洞的利用程序，已在 x86 模拟器上测试。其目的是利用 UAF 漏洞触发 AAR 原语来泄漏内核地址，并使用 AAW 原语覆盖 addrlimit，从而获得内核读写原语，使我们可以修改 credstruct 以实现本地权限提升 LPE。 致谢 https://googleprojectzero.blogspot.com/2019/11/bad-binder-android-in-wild-exploit.html...

CVE-2026-80842

A flaw was found in the Linux kernel's bridge multicast mcast component. A race condition in the handling of a master VLAN's multicast context during teardown can allow a network attacker to trigger a use-after-free vulnerability. This could lead to system instability or a denial of service DoS...

CVE-2026-80850

A flaw was found in the Linux kernel's TCP Authentication Option TCP-AO implementation. An unprivileged local attacker could exploit a race condition when a network device is detached from its Virtual Routing and Forwarding VRF interface. This could lead to a use-after-free vulnerability, causing...

CVE-2026-81003

A flaw was found in the Linux kernel's AFIUCV Advanced Program-to-Program Communication over IUCV network protocol implementation. The afiucvhsrcv function, responsible for receiving frames, does not properly filter incoming frames based on the ingress network device. This oversight allows a loca...

CVE-2026-80878

A flaw was found in the Linux kernel's AFS Andrew File System implementation. This issue occurs when afslookupvolumercu fails to acquire a volume, leading to a resource leak. A local attacker could potentially exploit this flaw to cause a denial of service due to resource exhaustion...

CVE-2026-80837
