kernel: scsi: mpi3mr: Use number of bits to manage bitmap sizes

In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Use number of bits to manage bitmap sizes To allocate bitmaps, the mpi3mr driver calculates sizes of bitmaps using byte as unit. However, bitmap helper functions assume that bitmaps are allocated using unsigned long...

kernel: Linux kernel: Denial of Service in scsi_ses due to enclosure with no components

A flaw was found in the Linux kernel's scsi: ses driver. A local attacker could trigger a kernel crash oops by attempting to manage a SCSI enclosure that reports having no components. This could lead to a Denial of Service DoS on the affected system...

kernel: scsi: scsi_dh_alua: Fix memleak for 'qdata' in alua_activate()

In the Linux kernel, the following vulnerability has been resolved: scsi: scsidhalua: Fix memleak for 'qdata' in aluaactivate If aluartpgqueue failed from aluaactivate, then 'qdata' is not freed, which will cause following memleak: unreferenced object 0xffff88810b2c6980 size 32: comm...

kernel: scsi: lpfc: Prevent lpfc_debugfs_lockstat_write() buffer overflow

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Prevent lpfcdebugfslockstatwrite buffer overflow A static code analysis tool flagged the possibility of buffer overflow when using copyfromuser for a debugfs entry. Currently, it is possible that copyfromuser copies...

kernel: scsi: mpi3mr: Fix missing mrioc->evtack_cmds initialization

A use-after-free vulnerability was found in the MPI3MR SCSI driver. The evtackcmds array is not properly initialized, causing invalid memory access via clearbit with incorrect bit indices during event acknowledgment...

kernel: scsi: mpi3mr: Fix mpi3mr_hba_port memory leak in mpi3mr_remove()

A flaw was found in the mpi3mr module in the Linux kernel. The missing release of memory allocated for mpi3mrhbaport will cause a memory leak, potentially impacting system stability and resulting in a denial of service...
