  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nx86/bugs: Make Safe-RET robust against interrupt injection\n\nAn attacker injecting interrupts while the Safe-RET mitigation executes\non machines affected by SRSO can neutralize the safe return sequence,\npotentially leading to data leakage through speculative execution.\n\nFixup register state as if the Safe-RET sequence executed successfully\nby \"emulating\" it, in a manner of speaking, and avoid executing a RET\ninstruction after returning from the interrupt.",
