But it is possible to attach a non-sleepable BPF program to a\nuprobe, and non-sleepable BPF programs are freed via normal RCU (see\n__bpf_prog_put_noref()). This leads to UAF of the bpf_prog because a normal\nRCU grace period does not imply a tasks-trace-RCU grace period.\n\nFix it by explicitly waiting for a tasks-trace-RCU grace period after\nremoving the attachment of a bpf_prog to a perf_event.\n\ud83d\udd22 Severity: CVSS_V3: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H\n\ud83d\uddd3\ufe0f Modified: 2025-01-06T15:30:59Z\n\ud83d\uddd3\ufe0f Published: 2024-12-27T15:31:56Z\n\ud83c\udff7\ufe0f CWE IDs: CWE-416\n\ud83d\udd17 References:\n1. https://nvd.nist.gov/vuln/detail/CVE-2024-5665\n2. https://git.kernel.org/stable/c/9245459a992d22fe0e92e988f49db1fec82c184a\n3. https://git.kernel.org/stable/c/9b53d2c2a38a1effc341d99be3f99faef104d\n4. https://git.kernel.org/stable/c/ef1b808e3bc98612feceedf985c2fbbeb28f956\n5. https://git.kernel.org/stable/c/f9f85df30118f3f411261e6682fc60ebcce23e5", "creation_timestamp": "2025-01-06T15:37:11.000000Z"}
