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:63 ...

In the Linux kernel, the following vulnerability has been resolved: jfs: fix array-index-out-of-bounds in diAlloc Currently there is not check against the agno of the iag while allocating new inodes to avoid fragmentation problem. Added the check which is required.

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: net: hns3: fix out-of-bounds access may occur when coalesce info is read via debugfs The hns3 driver define an array of string to show the coalesce info, but if the kernel adds a new mode or a new state, out-of-bounds access may occur when coalesce info is read via debugfs, this patch fix the problem.

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 p ...

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.

In the Linux kernel, the following vulnerability has been resolved: fs/jfs: Add check for negative db_l2nbperpage l2nbperpage is log2(number of blks per page), and the minimum legal value should be 0, not negative. In the case of l2nbperpage being negative, an error will occur when subsequently used as shift exponent. Syzbot reported this bug: UBSAN: shift-out-of-bounds in fs/jfs/jfs_dmap.c:7 ...

In the Linux kernel, the following vulnerability has been resolved: scsi: ibmvfc: Remove BUG_ON in the case of an empty event pool In practice the driver should never send more commands than are allocated to a queue's event pool. In the unlikely event that this happens, the code asserts a BUG_ON, and in the case that the kernel is not configured to crash on panic returns a junk event pointer fro ...

In the Linux kernel, the following vulnerability has been resolved: drm/amd: check num of link levels when update pcie param In SR-IOV environment, the value of pcie_table->num_of_link_levels will be 0, and num_of_levels - 1 will cause array index out of bounds

In the Linux kernel, the following vulnerability has been resolved: crypto: pcrypt - Fix hungtask for PADATA_RESET We found a hungtask bug in test_aead_vec_cfg as follows: INFO: task cryptomgr_test:391009 blocked for more than 120 seconds. "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. Call trace: __switch_to+0x98/0xe0 __schedule+0x6c4/0xf40 schedule+0xd8/0x1b4 sc ...
