    nvme: fix multipath crash caused by flush request when blktrace is enabled

    In the Linux kernel, the following vulnerability has been resolved: nvme: fix multipath crash caused by flush request when blktrace is enabled The flush request initialized by blk_kick_flush has NULL bio, and it may be dealt with nvme_end_req during io completion. When blktrace is enabled, nvme_trace_bio_complete with multipath activated trying to access NULL pointer bio from flush request results in the following crash: [ 2517.831677] BUG: kernel NULL pointer dereference, address: 000000000000001a [ 2517.835213] #PF: supervisor read access in kernel mode [ 2517.838724] #PF: error_code(0x0000) - not-present page [ 2517.842222] PGD 7b2d5106

    NFS: Fix an Oops in nfs_d_automount()

    In the Linux kernel, the following vulnerability has been resolved: NFS: Fix an Oops in nfs_d_automount() When mounting from a NFSv4 referral, path->dentry can end up being a negative dentry, so derive the struct nfs_server from the dentry itself instead.

    staging: pi433: fix memory leak with using debugfs_lookup()

    In the Linux kernel, the following vulnerability has been resolved: staging: pi433: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once. This requires saving off the root directory dentry to make creation of individual device subdirectories easier.

    accel/habanalabs: postpone mem_mgr IDR destruction to hpriv_release()

    In the Linux kernel, the following vulnerability has been resolved: accel/habanalabs: postpone mem_mgr IDR destruction to hpriv_release() The memory manager IDR is currently destroyed when user releases the file descriptor. However, at this point the user context might be still held, and memory buffers might be still in use. Later on, calls to release those buffers will fail due to not finding their handles in the IDR, leading to a memory leak. To avoid this leak, split the IDR destruction from the memory manager fini, and postpone it to hpriv_release() when there is no user context and no buffers are used.

    btrfs: fix deadlock when aborting transaction during relocation with scrub

    In the Linux kernel, the following vulnerability has been resolved: btrfs: fix deadlock when aborting transaction during relocation with scrub Before relocating a block group we pause scrub, then do the relocation and then unpause scrub. The relocation process requires starting and committing a transaction, and if we have a failure in the critical section of the transaction commit path (transaction state >= TRANS_STATE_COMMIT_START), we will deadlock if there is a paused scrub. That results in stack traces like the following: [42.479] BTRFS info (device sdc): relocating block group 53876686848 flags metadata|raid6 [42.936] BTRFS warni

    net/mlx5: Handle pairing of E-switch via uplink un/load APIs

    In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Handle pairing of E-switch via uplink un/load APIs In case user switch a device from switchdev mode to legacy mode, mlx5 first unpair the E-switch and afterwards unload the uplink vport. From the other hand, in case user remove or reload a device, mlx5 first unload the uplink vport and afterwards unpair the E-switch. The latter is causing a bug[1], hence, handle pairing of E-switch as part of uplink un/load APIs. [1] In case VF_LAG is used, every tc fdb flow is duplicated to the peer esw. However, the original esw keeps a pointer to this duplicated flow, not the

    In the Linux kernel, the following vulnerability has been resolved: RDMA/cxgb4: Fix potential null-ptr-deref in pass_establish() If get_ep_from_tid() fails to lookup non-NULL value for ep, ep is dereferenced later regardless of whether it is empty. This patch adds a simple sanity check to fix the issue. Found by Linux Verification Center (linuxtesting.org) with SVACE.
