英文标题:
perf: Revert to requiring CAP_SYS_ADMIN for uprobes
漏洞描述
中文描述:
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于uprobes未验证指令完整性，可能导致任意代码执行。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: perf: Revert to requiring CAP_SYS_ADMIN for uprobes Jann reports that uprobes can be used destructively when used in the middle of an instruction. The kernel only verifies there is a valid instruction at the requested offset, but due to variable instruction length cannot determine if this is an instruction as seen by the intended execution stream. Additionally, Mark Rutland notes that on architectures that mix data in the text segment (like arm64), a similar things can be done if the data word is 'mistaken' for an instruction. As such, require CAP_SYS_ADMIN for uprobes.
