Description
A flaw was found in the Linux kernel's Human Interface Device (HID) subsystem. A local attacker can trigger this vulnerability by unplugging certain HID devices when their drivers do not properly handle output reports. This can lead to memory corruption, potentially causing a denial of service or other unpredictable system behavior.
Statement
The default Red Hat Enterprise Linux kernel prevents unprivileged users from being able to use eBPF by the kernel.unprivileged_bpf_disabled sysctl. This would require a privileged user with CAP_SYS_ADMIN or root to be able to abuse this flaw reducing its attack space.
For the Red Hat Enterprise Linux 9 to confirm the current state, inspect the sysctl with the command:
cat /proc/sys/kernel/unprivileged_bpf_disabled
The setting of 1 would mean that unprivileged users can not use eBPF, mitigating the flaw.
