The following security bugs were fixed: - CVE-2021-26930: Fixed an improper error handling in blkback's grant mapping (XSA-365 bsc#1181843). - CVE-2021-26931: Fixed an issue where Linux kernel was treating grant mapping errors as bugs (XSA-362 bsc#1181753). - CVE-2021-26932: Fixed improper error handling issues in Linux grant mapping (XSA-361 bsc#1181747). - CVE-2020-28374: Fixed insufficient identifier checking in the LIO SCSI target code which could have been used by remote attackers to read or write files via directory traversal in an XCOPY request (bsc#178372). The following non-security bugs were fixed: - cifs: report error instead of invalid when revalidating a dentry fails (bsc#1177440). - xen/netback: fix spurious event detection for common event case (bsc#1182175).

checking in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are proxied via an attacker-selected backstore.

To service requests to the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be encountered. In one case, an error encountered earlier might be discarded by later processing, resulting in the caller assuming successful mapping, and hence subsequent operations trying to access space that wasn't mapped. In another case, internal state would be insufficiently updated, preventing safe recovery from the error. This affects drivers/block/xen-blkback/blkback.c.

Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests (such as out of memory conditions), it isn't correct to assume a plain bug. Memory allocations potentially causing such crashes occur only when Linux is running in PV mode, though. This affects drivers/block/xen-blkback/blkback.c and drivers/xen/xen-scsiback.c.

Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one is reported to the backend driver, and the backend driver then loops over the results, performing follow-up actions based on the success or failure of each operation. Unfortunately, when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively implying their success from the success of related batch elements. In other cases, errors resulting from one batch element lead to further batch elements not being inspected, and hence successful ones to not be possible to properly unmap upon error recovery. Only systems with Linux backends running in PV mode are vulnerable. Linux backends run in HVM / PVH modes are not vulnerable. This affects arch/*/xen/p2m.c and drivers/xen/gntdev.c.
