AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel. Users should update to patched versions of the linux-hwe-edge kernel as listed in the affected versions. Since this is a kernel-level issue, applying the official kernel updates from the vendor or distribution is the recommended remediation.
Description
A vulnerability in the Linux kernel's crypto subsystem (inside-secure/eip93) caused a kernel panic during driver detach due to multiple unregistrations of the same hash algorithm from a faulty iterator. This issue affects specific versions of the linux-hwe-edge kernel and has been resolved. The vulnerability has a medium severity score and does not impact confidentiality or integrity but causes availability disruption via kernel panic.
