USN-7100-2: Linux kernel vulnerabilities

Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a deni...

QEMU: Denial of Service via Improper Synchronization in QEMU NBD Server During Socket Closure

A flaw was found in the QEMU NBD Server. This vulnerability allows a denial of service DoS attack via improper synchronization during socket closure when a client keeps a socket open as the server is taken offline...

kernel: ext4: regenerate buddy after block freeing failed if under fc replay

A flaw was found in the Linux kernel's ext4 filesystem related to the fast commit replay process. During this process, blocks that are already marked as free can be incorrectly marked as free again, leading to the corruption of the buddy bitmap, which is used to track free and allocated blocks...

kernel: block: fix request.queuelist usage in flush

A vulnerability was found in the Linux kernel's block subsystem, where the issue arises when the request queue list is not properly initialized for the first request in the PREFLUSH/POSTFLUSH sequences, leading to potential kernel crashes due to improper list manipulation...

kernel: Linux kernel: Denial of Service via NULL pointer dereference in blk-cgroup

A flaw was found in the Linux kernel's block cgroup blk-cgroup component. A local attacker could exploit a race condition in the blkcgactivatepolicy function, where block group policy data blkgpolicydata is installed before it is fully initialized. This allows another function, iocweightwrite, to...

kernel: block: refine the EOF check in blkdev_iomap_begin

In the Linux kernel, the following vulnerability has been resolved: block: refine the EOF check in blkdeviomapbegin blkdeviomapbegin rounds down the offset to the logical block size before stashing it in iomap-offset and checking that it still is inside the inode size. Check the isize check to th...

kernel: usb: xhci: prevent potential failure in handle_tx_event() for Transfer events without TRB

In the Linux kernel, the following vulnerability has been resolved: usb: xhci: prevent potential failure in handletxevent for Transfer events without TRB Some transfer events don't always point to a TRB, and consequently don't have a endpoint ring. In these cases, function handletxevent should no...
