CVE-2022-30594 – kernel: Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP option
https://notcve.org/view.php?id=CVE-2022-30594
The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. El kernel de Linux versiones anteriores a 5.17.2, maneja inapropiadamente los permisos de seccomp. La ruta de código PTRACE_SEIZE permite a atacantes omitir las restricciones previstas al establecer el flag PT_SUSPEND_SECCOMP A flaw was found in the Linux kernel. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag, possibly disabling seccomp. • http://packetstormsecurity.com/files/167386/Kernel-Live-Patch-Security-Notice-LSN-0086-1.html http://packetstormsecurity.com/files/170362/Linux-PT_SUSPEND_SECCOMP-Permission-Bypass-Ptracer-Death-Race.html https://bugs.chromium.org/p/project-zero/issues/detail?id=2276 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.17.2 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ee1fee900537b5d9560e9f937402de5ddc8412f3 https://github.com/torvalds/linux/commit/ee1fee900537b5d9560e9f937402de • CWE-276: Incorrect Default Permissions CWE-862: Missing Authorization •
