  - Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to     multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV     device frontends are using the grant table interfaces for removing access rights of the backends in ways     being subject to race conditions, resulting in potential data leaks, data corruption by malicious     backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the     gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they     assume that a following removal of the granted access will always succeed, which is not true in case the     backend has mapped the granted page between those two operations. As a result the backend can keep access     to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.
    The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of     a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038     gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus,     9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no     longer in use, but the freeing of the related data page is not synchronized with dropping the granted     access. As a result the backend can keep access to the memory page even after it has been freed and then     re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to     revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which     can be triggered by the backend.

  - An issue was discovered in the Linux kernel before 5.16.12. drivers/net/usb/sr9700.c allows attackers to     obtain sensitive information from heap memory via crafted frame lengths from a device. (CVE-2022-26966)

  - A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and     net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap     objects and may cause a local privilege escalation threat. (CVE-2022-27666)

  - Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to     multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV     device frontends are using the grant table interfaces for removing access rights of the backends in ways     being subject to race conditions, resulting in potential data leaks, data corruption by malicious     backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the     gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they     assume that a following removal of the granted access will always succeed, which is not true in case the     backend has mapped the granted page between those two operations. As a result the backend can keep access     to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.
    The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of     a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038     gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus,     9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no     longer in use, but the freeing of the related data page is not synchronized with dropping the granted     access. As a result the backend can keep access to the memory page even after it has been freed and then     re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to     revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which     can be triggered by the backend.

  - Rogue backends can cause DoS of guests via high frequency events T[his CNA information record relates to     multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen offers the     ability to run PV backends in regular unprivileged guests, typically referred to as driver domains.
    Running PV backends in driver domains has one primary security advantage: if a driver domain gets     compromised, it doesn't have the privileges to take over the system. However, a malicious driver domain     could try to attack other guests via sending events at a high frequency leading to a Denial of Service in     the guest due to trying to service interrupts for elongated amounts of time. There are three affected     backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch     3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)

  - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record     relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]     Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming     new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).
    Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.
    (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in     its RX queue ring page and the next package would require more than one free slot, which may be the case     when using GSO, XDP, or software hashing. (CVE-2021-28714) (CVE-2021-28714, CVE-2021-28715)

  - An issue was discovered in fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A stall on CPU can occur     because a retry loop continually finds the same bad inode, aka CID-775c5033a0d1. (CVE-2021-28950)

  - A use-after-free flaw was found in the Linux kernel's Bluetooth subsystem in the way user calls connect to     the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the     system or escalate their privileges. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-3752)

  - A flaw was found in the Linux kernel. A use-after-free vulnerability in the NFC stack can lead to a threat     to confidentiality, integrity, and system availability. (CVE-2021-3760)

  - A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP     association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and     the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)

  - arch/mips/net/bpf_jit.c in the Linux kernel before 5.4.10 can generate undesirable machine code when     transforming unprivileged cBPF programs, allowing execution of arbitrary code within the kernel context.
