Byepervisor

Byepervisor 摘要 PS5 虚拟机监控器（hypervisor）漏洞，适用于 = 2.xx 固件。仓库中包含两个相互独立的漏洞及对应的漏洞利用链，任选其一即可使用。其中一个漏洞利用仅用于存档保留（/oldjumptableexploit），只需使用主漏洞利用链（QA flags 漏洞利用）即可。 该研究已在 hardwear.io NL 2024 大会上展示，幻灯片可在此处获取。演讲视频即将发布。 跳转表（Jump Table）漏洞利用 第一个漏洞利用了虚拟机监控器代码跳转表与客户机内核共享的漏洞，位于 /oldjumptableexploit/。通过劫持...

kernel: Arm Processors: Privilege escalation or information disclosure via writes to higher exception level resources

A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation TLBI operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local...
