    epoll: be better about file lifetimes

    In the Linux kernel, the following vulnerability has been resolved: epoll: be better about file lifetimes epoll can call out to vfs_poll() with a file pointer that may race with the last 'fput()'. That would make f_count go down to zero, and while the ep->mtx locking means that the resulting file pointer tear-down will be blocked until the poll returns, it means that f_count is already dead, and any use of it won't actually get a reference to the file any more: it's dead regardless. Make sure we have a valid ref on the file pointer before we call down to vfs_poll() from the epoll routines.

    ecryptfs: Fix buffer size for tag 66 packet

    In the Linux kernel, the following vulnerability has been resolved: ecryptfs: Fix buffer size for tag 66 packet The 'TAG 66 Packet Format' description is missing the cipher code and checksum fields that are packed into the message packet. As a result, the buffer allocated for the packet is 3 bytes too small and write_tag_66_packet() will write up to 3 bytes past the end of the buffer. Fix this by increasing the size of the allocation so the whole packet will always fit in the buffer. This fixes the below kasan slab-out-of-bounds bug: BUG: KASAN: slab-out-of-bounds in ecryptfs_generate_key_packet_set+0x7d6/0xde0 Write of size 1 at add

    gfs2: Fix potential glock use-after-free on unmount

    In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix potential glock use-after-free on unmount When a DLM lockspace is released and there ares still locks in that lockspace, DLM will unlock those locks automatically. Commit fb6791d100d1b started exploiting this behavior to speed up filesystem unmount: gfs2 would simply free glocks it didn't want to unlock and then release the lockspace. This didn't take the bast callbacks for asynchronous lock contention notifications into account, which remain active until until a lock is unlocked or its lockspace is released. To prevent those callbacks from accessing deallocate

    wifi: carl9170: add a proper sanity check for endpoints

    In the Linux kernel, the following vulnerability has been resolved: wifi: carl9170: add a proper sanity check for endpoints Syzkaller reports [1] hitting a warning which is caused by presence of a wrong endpoint type at the URB sumbitting stage. While there was a check for a specific 4th endpoint, since it can switch types between bulk and interrupt, other endpoints are trusted implicitly. Similar warning is triggered in a couple of other syzbot issues [2]. Fix the issue by doing a comprehensive check of all endpoints taking into account difference between high- and full-speed configuration. [1] Syzkaller report: ... WARNING: CPU: 0 PID:

    scsi: bfa: Ensure the copied buf is NUL terminated

    In the Linux kernel, the following vulnerability has been resolved: scsi: bfa: Ensure the copied buf is NUL terminated Currently, we allocate a nbytes-sized kernel buffer and copy nbytes from userspace to that buffer. Later, we use sscanf on this buffer but we don't ensure that the string is terminated inside the buffer, this can lead to OOB read when using sscanf. Fix this issue by using memdup_user_nul instead of memdup_user.

    net: fec: remove .ndo_poll_controller to avoid deadlocks

    In the Linux kernel, the following vulnerability has been resolved: net: fec: remove .ndo_poll_controller to avoid deadlocks There is a deadlock issue found in sungem driver, please refer to the commit ac0a230f719b ("eth: sungem: remove .ndo_poll_controller to avoid deadlocks"). The root cause of the issue is that netpoll is in atomic context and disable_irq() is called by .ndo_poll_controller interface of sungem driver, however, disable_irq() might sleep. After analyzing the implementation of fec_poll_controller(), the fec driver should have the same issue. Due to the fec driver uses NAPI for TX completions, the .ndo_poll_controller is unn

    Bluetooth: L2CAP: Fix div-by-zero in l2cap_le_flowctl_init()

    In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix div-by-zero in l2cap_le_flowctl_init() l2cap_le_flowctl_init() can cause both div-by-zero and an integer overflow since hdev->le_mtu may not fall in the valid range. Move MTU from hci_dev to hci_conn to validate MTU and stop the connection process earlier if MTU is invalid. Also, add a missing validation in read_buffer_size() and make it return an error value if the validation fails. Now hci_conn_add() returns ERR_PTR() as it can fail due to the both a kzalloc failure and invalid MTU value. divide error: 0000 [#1] PREEMPT SMP KASAN NOPTI CPU: 0 PID:

The length of the drm_event was set to the parent structure instead of to the drm_vmw_event_fence which is supposed to be read. drm_read uses the length parameter to copy the event to the user space thus resuling in oob reads.

    scsi: lpfc: Move NPIV's transport unregistration to after resource clean up

    In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Move NPIV's transport unregistration to after resource clean up There are cases after NPIV deletion where the fabric switch still believes the NPIV is logged into the fabric. This occurs when a vport is unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the fabric. Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including the fabric D_ID, removes the last ndlp reference and frees the ndlp rport object. This sometimes causes the race condition where the final DA_ID and LOGO are skipped from being sent to the fabric switch.

    firewire: ohci: mask bus reset interrupts between ISR and bottom half

    In the Linux kernel, the following vulnerability has been resolved: firewire: ohci: mask bus reset interrupts between ISR and bottom half In the FireWire OHCI interrupt handler, if a bus reset interrupt has occurred, mask bus reset interrupts until bus_reset_work has serviced and cleared the interrupt. Normally, we always leave bus reset interrupts masked. We infer the bus reset from the self-ID interrupt that happens shortly thereafter. A scenario where we unmask bus reset interrupts was introduced in 2008 in a007bb857e0b26f5d8b73c2ff90782d9c0972620: If OHCI_PARAM_DEBUG_BUSRESETS (8) is set in the debug parameter bitmask, we will unmask b

Recently, commit d47151b79e32 ("nfs: expose /proc/net/sunrpc/nfs in net namespaces") converted the procfs to per-netns and made the problem more visible. Even when rpc_proc_register() fails, nfs_net_init() could succeed, and thus nfs_net_exit() will be called while destroying the netns. The
