CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel on x86 architectures, specifically related to the Safe-RET mitigation against speculative execution attacks. An attacker could exploit this flaw by injecting interrupts during the Safe-RET execution, potentially leading to data leakage. Organizations using affected Linux systems, particularly those with high-security requirements, should prioritize applying the fix to mitigate the risk of information exposure.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: x86/bugs: Make Safe-RET robust against interrupt injection An attacker injecting interrupts while the Safe-RET mitigation executes on machines affected by SRSO can neutralize the safe return sequence, potentially leading to data leakage through speculative execution. Fixup register state as if the Safe-RET sequence executed successfully by "emulating" it, in a manner of speaking, and avoid executing a RET instruction after returning from the interrupt.
