In the Linux kernel, the following vulnerability has been resolved:
dyndbg: fix old BUG_ON in >control parser
Fix a BUG_ON from 2009. Even if it looks "unreachable" (I didn't
really look), lets make sure by removing it, doing pr_err and return
-EINVAL instead.
In the Linux kernel, the following vulnerability has been resolved:
dyndbg: fix old BUG_ON in >control parser
The Linux kernel CVE team has assigned CVE-2024-35947 to this issue.
Upstream advisory:
https://lore.kernel.org/linux-cve-announce/2024051952-CVE-2024-35947-09bb@gregkh/T
Отчет
This vulnerability is rated as having a Low severity because triggering the assertion failure requires privileged local access to write to the kernel's dynamic debug control interface. In default Red Hat Enterprise Linux installations, the debugfs filesystem and dynamic debug control endpoints are restricted to root or processes with administrative privileges. Consequently, unprivileged local users cannot exploit this flaw to crash the system or escalate privileges.
