Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

CVE-2021-43976

    Zekun Shen and Brendan Dolan-Gavitt discovered a flaw in the
    mwifiex_usb_recv() function of the Marvell WiFi-Ex USB Driver. An
    attacker able to connect a crafted USB device can take advantage of
    this flaw to cause a denial of service.

CVE-2022-0330

    Sushma Venkatesh Reddy discovered a missing GPU TLB flush in the
    i915 driver, resulting in denial of service or privilege escalation.

CVE-2022-0435

    Samuel Page and Eric Dumazet reported a stack overflow in the
    networking module for the Transparent Inter-Process Communication
    (TIPC) protocol, resulting in denial of service or potentially the
    execution of arbitrary code.

CVE-2022-0516

    It was discovered that an insufficient check in the KVM subsystem
    for s390x could allow unauthorized memory read or write access.

CVE-2022-0847

    Max Kellermann discovered a flaw in the handling of pipe buffer
    flags. An attacker can take advantage of this flaw for local
    privilege escalation.

CVE-2022-22942

    It was discovered that wrong file file descriptor handling in the
    VMware Virtual GPU driver (vmwgfx) could result in information leak
    or privilege escalation.

CVE-2022-24448

    Lyu Tao reported a flaw in the NFS implementation in the Linux
    kernel when handling requests to open a directory on a regular file,
    which could result in a information leak.

CVE-2022-24959

    A memory leak was discovered in the yam_siocdevprivate() function of
    the YAM driver for AX.25, which could result in denial of service.

CVE-2022-25258

    Szymon Heidrich reported the USB Gadget subsystem lacks certain
    validation of interface OS descriptor requests, resulting in memory
    corruption.

CVE-2022-25375

    Szymon Heidrich reported that the RNDIS USB gadget lacks validation
    of the size of the RNDIS_MSG_SET command, resulting in information
    leak from kernel memory.

For the stable distribution (bullseye), these problems have been fixed in
version 5.10.92-2.

We recommend that you upgrade your linux packages.
