A vulnerability in the Linux kernel's crypto subsystem (inside-secure/eip93) caused a panic on platforms lacking full hardware support for certain crypto algorithms. The issue arose because the unregister function removed all algorithms regardless of hardware support, leading to instability. This vulnerability has been resolved.
AI Analysis
Technical Summary
The Linux kernel's crypto module inside-secure/eip93 uses an options register to indicate which crypto algorithms are implemented in silicon. Supported algorithms are registered accordingly, but the unregister function previously removed all algorithms indiscriminately, including those not supported by the hardware. This caused kernel panic on platforms missing some hardware implementations. The vulnerability has been fixed to unregister only the available algorithms, preventing such panics.
Potential Impact
This vulnerability results in a denial of service (kernel panic) on affected platforms that do not have all crypto algorithms implemented in silicon. There is no impact on confidentiality or integrity. The CVSS score is 5.5 (medium severity) reflecting the local attack vector, low complexity, and denial of service impact.
Mitigation Recommendations
A fix is available as the vulnerability has been resolved in the Linux kernel. Users should update to the fixed kernel version provided by their distribution. Since this is not a cloud service, remediation requires applying the official kernel update. Patch status is not explicitly confirmed in the provided data; users should consult their vendor or distribution advisory for the exact fixed versions and update instructions.
