CVE-2021-47328

A vulnerability was found in the Linux kernel's iSCSI subsystem, where the iscsiconnteardown function could use a freed connection during resets. This occurs if the connection is freed while still being accessed by error handler threads, potentially causing system instability or crashes. Mitigati...

CVE-2021-47337

A vulnerability was found in the Linux kernel's SCSI subsystem. The issue occurs when the system tries to stop an error handler thread that failed to start; if the thread fails to spawn, the kernel may dereference a bad pointer, leading to potential system crash. Mitigation Red Hat has investigat...

kernel: scsi: core: Remove the /proc/scsi/${proc_name} directory earlier

In the Linux kernel, the following vulnerability has been resolved: scsi: core: Remove the /proc/scsi/$procname directory earlier Remove the /proc/scsi/$procname directory earlier to fix a race condition between unloading and reloading kernel modules. This fixes a bug introduced in 2009 by commit...

kernel: scsi: qla2xxx: Wait for io return on terminate rport

A flaw was found in the Linux kernel’s SCSI driver component qla2xxx used with FCP-2 devices. When the terminaterportio function is invoked , the driver may exit cleanup before all outstanding I/O operations have returned. This can lead to a use-after-free condition when resources are freed while...

kernel: scsi: qla2xxx: Fix deletion race condition

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix deletion race condition System crash when using debug kernel due to link list corruption. The cause of the link list corruption is due to session deletion was allowed to queue up twice. Here's the internal trac...

kernel: scsi: qla2xxx: Pointer may be dereferenced

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Pointer may be dereferenced Klocwork tool reported pointer 'rport' returned from call to function fcbsgtorport may be NULL and will be dereferenced. Add a fix to validate rport before dereferencing...

kernel: scsi: qla2xxx: Remove unused nvme_ls_waitq wait queue

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Remove unused nvmelswaitq wait queue System crash when qla2x00startspsp returns error code EGAIN and wakeup gets called for uninitialized wait queue sp-nvmelswaitq. qla2xxx 0000:37:00.1-2121:5: Returning existing...

kernel: scsi: qla2xxx: Array index may go out of bound

A flaw was found in the Linux kernel qla2xxx SCSI driver. A static analysis tool reported that the array vha-hoststr, sized to hold 16 characters, could be indexed with values outside its valid range, potentially leading to out-of-bounds writes. The root cause was the use of sprintf without...

kernel: RDMA/srpt: Add a check for valid 'mad_agent' pointer

A flaw was addressed in the Linux kernel’s RDMA SRPT SCSI RDMA Protocol Target subsystem. When unregistering a MAD Management Datagram agent, the SRPT module previously performed a non-NULL check on the madagent pointer before invoking ibunregistermadagent. Under rare timing...
