| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.17.2
Description
The issue is related to the mishandling of seccomp permissions in the Linux kernel. Specifically, the PTRACE SEIZE code path allows attackers to bypass intended restrictions on setting the
PT SUSPEND SECCOMP flag. This can potentially allow an attacker to elevate their privileges.Recommendations
For Linux kernel versions prior to 5.17.2, update to version 5.17.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of the
PTRACE SEIZE code path to minimize the risk of exploitation.Exploit
