[PATCH openEuler-1.0-LTS] nilfs2: fix general protection fault in nilfs_btree_insert()
by Yang Yingliang 22 Aug '24

22 Aug '24

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v4.19.271 commit d9fde9eab1766170ff2ade67d09178d2cfd78749 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IALLDY CVE: CVE-2023-52900 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------- commit 7633355e5c7f29c049a9048e461427d1d8ed3051 upstream. If nilfs2 reads a corrupted disk image and tries to reads a b-tree node block by calling __nilfs_btree_get_block() against an invalid virtual block address, it returns -ENOENT because conversion of the virtual block address to a disk block address fails. However, this return value is the same as the internal code that b-tree lookup routines return to indicate that the block being searched does not exist, so functions that operate on that b-tree may misbehave. When nilfs_btree_insert() receives this spurious 'not found' code from nilfs_btree_do_lookup(), it misunderstands that the 'not found' check was successful and continues the insert operation using incomplete lookup path data, causing the following crash: general protection fault, probably for non-canonical address 0xdffffc0000000005: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range [0x0000000000000028-0x000000000000002f] ...

By returning -EINVAL, it propagates without glitches, and for all relevant b-tree operations, functions in the upper bmap layer output an error message indicating corrupted b-tree metadata via nilfs_bmap_convert_error(), and code -EIO will be eventually returned as it should be.

[PATCH openEuler-22.03-LTS-SP1] xhci: Fix null pointer dereference when host dies

From: Mathias Nyman <mathias.nyman(a)linux.intel.com> stable inclusion from stable-v5.10.165 commit 081105213ff6f661c114781d469233c7d0e09c2e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IALLDG CVE: CVE-2023-52898 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a2bc47c43e70cf904b1af49f76d572326c08bca7 upstream. Make sure xhci_free_dev() and xhci_kill_endpoint_urbs() do not race and cause null pointer dereference when host suddenly dies. Usb core may call xhci_free_dev() which frees the xhci->devs[slot_id] virt device at the same time that xhci_kill_endpoint_urbs() tries to loop through all the device's endpoints, checking if there are any cancelled urbs left to give back. hold the xhci spinlock while freeing the virt device Cc: stable(a)vger.kernel.org Signed-off-by: Mathias Nyman <mathias.nyman(a)linux.intel.com> Link: https://lore.kernel.org/r/20230116142216.1141605-4-mathias.nyman@linux.inte… Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: sanglipeng <sanglipeng1(a)jd.com> Signed-off-by: Zheng Yejian <zhengyejian1(a)huawei.com> --- drivers/usb/host/xhci.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/drivers/usb/host/xhci.c b/drivers/usb/host/xhci.c index 9ed196947967..57ca3c21e527 100644 --- a/drivers/usb/host/xhci.c +++ b/drivers/usb/host/xhci.c @@ -3913,6 +3913,7 @@ static void xhci_free_dev(struct usb_hcd *hcd, struct usb_device *udev) struct xhci_hcd *xhci = hcd_to_xhci(hcd); struct xhci_virt_device *virt_dev; struct xhci_slot_ctx *slot_ctx; + unsigned long flags; int i, ret; /* @@ -3941,7 +3942,11 @@ static void xhci_free_dev(struct usb_hcd *hcd, struct usb_device *udev) } virt_dev->udev = NULL; xhci_disable_slot(xhci, udev->slot_id); + + spin_lock_irqsave(&xhci->lock, flags); xhci_free_virt_device(xhci, udev->slot_id); + spin_unlock_irqrestore(&xhci->lock, flags); + } int xhci_disable_slot(struct xhci_hcd *xhci, u32 slot_id) -- 2.25.1
