  - 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.

  - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create     user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to     a use-after-free. (CVE-2022-32250)

  - A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain     privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past     commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 (CVE-2022-1055)

  - A use-after-free vulnerability was found in the Linux kernel in drivers/net/hamradio. This flaw allows a     local attacker with a user privilege to cause a denial of service (DOS) when the mkiss or sixpack device     is detached and reclaim resources early. (CVE-2022-1195)

  - A use-after-free vulnerabilitity was discovered in drivers/net/hamradio/6pack.c of linux that allows an     attacker to crash linux kernel by simulating ax25 device using 6pack driver from user space.
    (CVE-2022-1198)

  - A flaw was found in the Linux kernel. This flaw allows an attacker to crash the Linux kernel by simulating     amateur radio from the user space, resulting in a null-ptr-deref vulnerability and a use-after-free     vulnerability. (CVE-2022-1199)

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1183-1 advisory.

  - In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota     tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a     corrupted quota file. (CVE-2021-45868)

  - A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to     userspace. (CVE-2022-0850)

    This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)

  - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a     use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel     information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)

  - The check_alu_op() function in kernel/bpf/verifier.c in the Linux kernel through v5.16-rc5 did not     properly update bounds while handling the mov32 instruction, which allows local users to obtain     potentially sensitive address information, aka a pointer leak. (CVE-2021-45402)

  - 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. CVE-2022-23042 (CVE-2022-23036, CVE-2022-23037, CVE-2022-23038,     CVE-2022-23039, CVE-2022-23040, CVE-2022-23041, CVE-2022-23042)

  - 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)
