[PATCH openEuler-1.0-LTS] xhci: Remove device endpoints from bandwidth list when freeing the device
by Chen Jinghuang 28 Oct '25

28 Oct '25

From: Mathias Nyman <mathias.nyman(a)linux.intel.com> stable inclusion from stable-v4.19.264 commit cebbc8d335d6bcc1316584f779c08f80287c6af8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID0U9S CVE: CVE-2022-50470 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 5aed5b7c2430ce318a8e62f752f181e66f0d1053 upstream. Endpoints are normally deleted from the bandwidth list when they are dropped, before the virt device is freed. If xHC host is dying or being removed then the endpoints aren't dropped cleanly due to functions returning early to avoid interacting with a non-accessible host controller. So check and delete endpoints that are still on the bandwidth list when freeing the virt device. Solves a list_del corruption kernel crash when unbinding xhci-pci, caused by xhci_mem_cleanup() when it later tried to delete already freed endpoints from the bandwidth list. This only affects hosts that use software bandwidth checking, which currenty is only the xHC in intel Panther Point PCH (Ivy Bridge) Cc: stable(a)vger.kernel.org Reported-by: Marek Marczykowski-Górecki <marmarek(a)invisiblethingslab.com> Tested-by: Marek Marczykowski-Górecki <marmarek(a)invisiblethingslab.com> Signed-off-by: Mathias Nyman <mathias.nyman(a)linux.intel.com> Link: https://lore.kernel.org/r/20221024142720.4122053-5-mathias.nyman@intel.com Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Chen Jinghuang <chenjinghuang2(a)huawei.com> --- drivers/usb/host/xhci-mem.c | 20 ++++++++++++-------- 1 file changed, 12 insertions(+), 8 deletions(-) diff --git a/drivers/usb/host/xhci-mem.c b/drivers/usb/host/xhci-mem.c index 76d13bed7c15..0dfba22250f6 100644 --- a/drivers/usb/host/xhci-mem.c +++ b/drivers/usb/host/xhci-mem.c @@ -906,15 +906,19 @@ void xhci_free_virt_device(struct xhci_hcd *xhci, int slot_id) if (dev->eps[i].stream_info) xhci_free_stream_info(xhci, dev->eps[i].stream_info); - /* Endpoints on the TT/root port lists should have been removed - * when usb_disable_device() was called for the device. - * We can't drop them anyway, because the udev might have gone - * away by this point, and we can't tell what speed it was. + /* + * Endpoints are normally deleted from the bandwidth list when + * endpoints are dropped, before device is freed. + * If host is dying or being removed then endpoints aren't + * dropped cleanly, so delete the endpoint from list here. + * Only applicable for hosts with software bandwidth checking. */ - if (!list_empty(&dev->eps[i].bw_endpoint_list)) - xhci_warn(xhci, "Slot %u endpoint %u " - "not removed from BW list!\n", - slot_id, i); + + if (!list_empty(&dev->eps[i].bw_endpoint_list)) { + list_del_init(&dev->eps[i].bw_endpoint_list); + xhci_dbg(xhci, "Slot %u endpoint %u not removed from BW list!\n", + slot_id, i); + } } /* If this is a hub, free the TT(s) from the TT list */ xhci_free_tt_info(xhci, dev, slot_id); -- 2.34.1

[PATCH openEuler-1.0-LTS] mm/slub: avoid accessing metadata when pointer is invalid in object_err()

From: Li Qiong <liqiong(a)nfschina.com> stable inclusion from stable-v5.4.299 commit 872f2c34ff232af1e65ad2df86d61163c8ffad42 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID0R2Y CVE: CVE-2025-39902 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit b4efccec8d06ceb10a7d34d7b1c449c569d53770 ] object_err() reports details of an object for further debugging, such as the freelist pointer, redzone, etc. However, if the pointer is invalid, attempting to access object metadata can lead to a crash since it does not point to a valid object. One known path to the crash is when alloc_consistency_checks() determines the pointer to the allocated object is invalid because of a freelist corruption, and calls object_err() to report it. The debug code should report and handle the corruption gracefully and not crash in the process. In case the pointer is NULL or check_valid_pointer() returns false for the pointer, only print the pointer value and skip accessing metadata.
