[PATCH OLK-6.6] bpf,perf: Fix invalid prog_array access in perf_event_detach_bpf_prog

From: Jiri Olsa <jolsa(a)kernel.org> stable inclusion from stable-v6.6.67 commit c2b6b47662d5f2dfce92e5ffbdcac8229f321d9d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAN1 CVE: CVE-2024-56665 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 978c4486cca5c7b9253d3ab98a88c8e769cb9bbd upstream. Syzbot reported [1] crash that happens for following tracing scenario: - create tracepoint perf event with attr.inherit=1, attach it to the process and set bpf program to it - attached process forks -> chid creates inherited event the new child event shares the parent's bpf program and tp_event (hence prog_array) which is global for tracepoint - exit both process and its child -> release both events - first perf_event_detach_bpf_prog call will release tp_event->prog_array and second perf_event_detach_bpf_prog will crash, because tp_event->prog_array is NULL The fix makes sure the perf_event_detach_bpf_prog checks prog_array is valid before it tries to remove the bpf program from it.

[PATCH OLK-5.10] i40e: fix race condition by adding filter's intermediate sync state
by Zhang Changzhong 02 Jan '25

02 Jan '25

From: Aleksandr Loktionov <aleksandr.loktionov(a)intel.com> mainline inclusion from mainline-v6.12-rc7 commit f30490e9695ef7da3d0899c6a0293cc7cd373567 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5KRJ CVE: CVE-2024-53088 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Fix a race condition in the i40e driver that leads to MAC/VLAN filters becoming corrupted and leaking. Address the issue that occurs under heavy load when multiple threads are concurrently modifying MAC/VLAN filters by setting mac and port VLAN. 1. Thread T0 allocates a filter in i40e_add_filter() within i40e_ndo_set_vf_port_vlan(). 2. Thread T1 concurrently frees the filter in __i40e_del_filter() within i40e_ndo_set_vf_mac(). 3. Subsequently, i40e_service_task() calls i40e_sync_vsi_filters(), which refers to the already freed filter memory, causing corruption. Reproduction steps: 1. Spawn multiple VFs. 2. Apply a concurrent heavy load by running parallel operations to change MAC addresses on the VFs and change port VLANs on the host. 3. Observe errors in dmesg: "Error I40E_AQ_RC_ENOSPC adding RX filters on VF XX, please set promiscuous on manually for VF XX". Exact code for stable reproduction Intel can't open-source now. The fix involves implementing a new intermediate filter state, I40E_FILTER_NEW_SYNC, for the time when a filter is on a tmp_add_list. These filters cannot be deleted from the hash list directly but must be removed using the full process.
