In the Linux kernel, the following vulnerability has been resolved: net/smc: check smcd_v2_ext_offset when receiving proposal msg When receiving… (CVE-2024-47408)
A vulnerability in the Linux kernel's net/smc component related to handling the smcd_v2_ext_offset field in proposal messages has been resolved. The field, originating from remote clients, was not properly validated, allowing values exceeding the maximum to cause out-of-bounds memory access and potential kernel crashes. The issue has been fixed by adding a check on smcd_v2_ext_offset before use.
AI Analysis
Technical Summary
CVE-2024-47408 addresses a flaw in the Linux kernel's net/smc subsystem where the smcd_v2_ext_offset field in proposal messages received from remote clients was not properly validated. This lack of validation could lead to accessing incorrect memory addresses, resulting in a denial-of-service condition via kernel crash. The vulnerability is mitigated by a patch that verifies the smcd_v2_ext_offset value before it is used.
Potential Impact
The vulnerability can cause a denial-of-service (DoS) by crashing the kernel when processing malformed proposal messages with an invalid smcd_v2_ext_offset value. There is no indication of confidentiality or integrity impact.
Mitigation Recommendations
A patch has been applied to the Linux kernel that checks the smcd_v2_ext_offset value before use, preventing out-of-bounds access and crashes. Users should update their Linux kernel to a version including this fix. No additional mitigation steps are indicated.
