  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nperf: Fix __perf_event_overflow() vs perf_remove_from_context() race\n\nMake sure that __perf_event_overflow() runs with IRQs disabled for all\npossible callchains. Specifically the software events can end up running\nit with only preemption disabled.\n\nThis opens up a race vs perf_event_exit_event() and friends that will go\nand free various things the overflow path expects to be present, like\nthe BPF program.",

      "scenario": "AV:L - The vulnerability is triggered through the perf_event_open() syscall and closing the event fd, both local operations requiring local system access.\nAC:L - The attacker controls both sides of the race: one thread triggers the software perf event overflow while another thread closes the fd. The attacker creates and controls the race timing, making it reliably exploitable.\nPR:L - An unprivileged local user can create software perf events with exclude_kernel=1 under the default perf_event_paranoid=2 setting. No special capabilities are required.\nUI:N - No user interaction is needed. The attacker creates the perf event, triggers it, and races the close() independently.\nS:U - The vulnerability results in kernel privilege escalation within the same security authority (kernel context). There is no crossing of virtualization or sandbox boundaries.\nC:H - The use-after-free on the perf_event structure gives the attacker control over freed memory contents via heap spraying, enabling arbitrary kernel memory reads through controlled function pointer calls.\nI:H - The UAF includes a function pointer call (event->overflow_handler) from potentially attacker-controlled freed memory, providing a direct code execution primitive for arbitrary kernel code execution.\nA:H - The use-after-free will cause kernel crashes (oops/panic) even without sophisticated exploitation, as accessing freed memory leads to immediate instability."
