Vulnerability from cvelistv5
Published

Modified

Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: perf: Fix __perf_event_overflow() vs perf_remove_from_context() race Make sure that __perf_event_overflow() runs with IRQs disabled for all possible callchains. Specifically the software events can end up running it with only preemption disabled. This opens up a race vs perf_event_exit_event() and friends that will go and free various things the overflow path expects to be present, like the BPF program.

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-\u003eoverflow_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."
