    scsi: libfc: Fix potential NULL pointer dereference in fc_lport_ptp_setup()

    In the Linux kernel, the following vulnerability has been resolved: scsi: libfc: Fix potential NULL pointer dereference in fc_lport_ptp_setup() fc_lport_ptp_setup() did not check the return value of fc_rport_create() which can return NULL and would cause a NULL pointer dereference. Address this issue by checking return value of fc_rport_create() and log error message on fc_rport_create() failed.

    scsi: hisi_sas: Set debugfs_dir pointer to NULL after removing debugfs

    In the Linux kernel, the following vulnerability has been resolved: scsi: hisi_sas: Set debugfs_dir pointer to NULL after removing debugfs If init debugfs failed during device registration due to memory allocation failure, debugfs_remove_recursive() is called, after which debugfs_dir is not set to NULL. debugfs_remove_recursive() will be called again during device removal. As a result, illegal pointer is accessed. [ 1665.467244] hisi_sas_v3_hw 0000:b4:02.0: failed to init debugfs! ...

    ALSA: hda: Fix possible null-ptr-deref when assigning a stream

    In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: Fix possible null-ptr-deref when assigning a stream While AudioDSP drivers assign streams exclusively of HOST or LINK type, nothing blocks a user to attempt to assign a COUPLED stream. As supplied substream instance may be a stub, what is the case when code-loading, such scenario ends with null-ptr-deref.

    In the Linux kernel, the following vulnerability has been resolved: fs/jfs: Add validity check for db_maxag and db_agpref Both db_maxag and db_agpref are used as the index of the db_agfree array, but there is currently no validity check for db_maxag and db_agpref, which can lead to errors. The following is related bug reported by Syzbot: UBSAN: array-index-out-of-bounds in fs/jfs/jfs_dmap.c:639:20 index 7936 is out of range for type 'atomic_t[128]' Add checking that the values of db_maxag and db_agpref are valid indexes for the db_agfree array.

    SUNRPC: Fix RPC client cleaned up the freed pipefs dentries

    In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fix RPC client cleaned up the freed pipefs dentries RPC client pipefs dentries cleanup is in separated rpc_remove_pipedir() workqueue,which takes care about pipefs superblock locking. In some special scenarios, when kernel frees the pipefs sb of the current client and immediately alloctes a new pipefs sb, rpc_remove_pipedir function would misjudge the existence of pipefs sb which is not the one it used to hold. As a result, the rpc_remove_pipedir would clean the released freed pipefs dentries. To fix this issue, rpc_remove_pipedir should check whether the current p

    jfs: fix array-index-out-of-bounds in dbFindLeaf

    In the Linux kernel, the following vulnerability has been resolved: jfs: fix array-index-out-of-bounds in dbFindLeaf Currently while searching for dmtree_t for sufficient free blocks there is an array out of bounds while getting element in tp->dm_stree. To add the required check for out of bound we first need to determine the type of dmtree. Thus added an extra parameter to dbFindLeaf so that the type of tree can be determined and the required check can be applied.

    ipvlan: add ipvlan_route_v6_outbound() helper

    In the Linux kernel, the following vulnerability has been resolved: ipvlan: add ipvlan_route_v6_outbound() helper Inspired by syzbot reports using a stack of multiple ipvlan devices. Reduce stack size needed in ipvlan_process_v6_outbound() by moving the flowi6 struct used for the route lookup in an non inlined helper. ipvlan_route_v6_outbound() needs 120 bytes on the stack, immediately reclaimed. Also make sure ipvlan_process_v4_outbound() is not inlined. We might also have to lower MAX_NEST_DEV, because only syzbot uses setups with more than four stacked devices.

    i2c: core: Run atomic i2c xfer when !preemptible

    In the Linux kernel, the following vulnerability has been resolved: i2c: core: Run atomic i2c xfer when !preemptible Since bae1d3a05a8b, i2c transfers are non-atomic if preemption is disabled. However, non-atomic i2c transfers require preemption (e.g. in wait_for_completion() while waiting for the DMA). panic() calls preempt_disable_notrace() before calling emergency_restart(). Therefore, if an i2c device is used for the restart, the xfer should be atomic. This avoids warnings like: [ 12.667612] WARNING: CPU: 1 PID: 1 at kernel/rcu/tree_plugin.h:318 rcu_note_context_switch+0x33c/0x6b0 [ 12.676926] Voluntary context switch within RCU r

    bonding: stop the device in bond_setup_by_slave()

    In the Linux kernel, the following vulnerability has been resolved: bonding: stop the device in bond_setup_by_slave() Commit 9eed321cde22 ("net: lapbether: only support ethernet devices") has been able to keep syzbot away from net/lapb, until today. In the following splat [1], the issue is that a lapbether device has been created on a bonding device without members. Then adding a non ARPHRD_ETHER member forced the bonding master to change its type. The fix is to make sure we call dev_close() in bond_setup_by_slave() so that the potential linked lapbether devices (or any other devices having assumptions on the physical device) are removed.

    usb: config: fix iteration issue in 'usb_get_bos_descriptor()'

    In the Linux kernel, the following vulnerability has been resolved: usb: config: fix iteration issue in 'usb_get_bos_descriptor()' The BOS descriptor defines a root descriptor and is the base descriptor for accessing a family of related descriptors. Function 'usb_get_bos_descriptor()' encounters an iteration issue when skipping the 'USB_DT_DEVICE_CAPABILITY' descriptor type. This results in the same descriptor being read repeatedly. To address this issue, a 'goto' statement is introduced to ensure that the pointer and the amount read is updated correctly. This ensures that the function iterates to the next descriptor instead of reading th

    s390/dasd: protect device queue against concurrent access

    In the Linux kernel, the following vulnerability has been resolved: s390/dasd: protect device queue against concurrent access In dasd_profile_start() the amount of requests on the device queue are counted. The access to the device queue is unprotected against concurrent access. With a lot of parallel I/O, especially with alias devices enabled, the device queue can change while dasd_profile_start() is accessing the queue. In the worst case this leads to a kernel panic due to incorrect pointer accesses. Fix this by taking the device lock before accessing the queue and counting the requests. Additionally the check for a valid profile data poi
