More information:

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

  • CVE-2022-22942

    It was discovered that wrong 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.
