The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:0777 advisory.
- kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)
- kernel: use-after-free in RDMA listen() (CVE-2021-4028)
- kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)
- kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS (CVE-2022-0435)
- kernel: missing check in ioctl allows kernel memory read/write (CVE-2022-0516)
- kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.\n (CVE-2022-0492)\n\n - kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)\n\n - kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)\n\n - A vulnerability was found in kvm_s390_guest_sida_op in the arch/s390/kvm/kvm-s390.c function in KVM for s390 in the Linux kernel. This flaw allows a local attacker with a normal user privilege to obtain unauthorized memory write access. This flaw affects Linux kernel versions prior to 5.17-rc4.\n (CVE-2022-0516)\n\n - A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)\n\n - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:\n Upstream kernel (CVE-2021-0920)\n\n - kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS (CVE-2022-0435)\n\n - A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser.

advisory.\n\n - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).\n (CVE-2021-43976)\n\n - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor. (CVE-2022-24448)\n\n - An issue was discovered in the Linux kernel before 5.16.5. There is a memory leak in yam_siocdevprivate in drivers/net/hamradio/yam.c. (CVE-2022-24959)\n\n - An issue was discovered in drivers/usb/gadget/composite.c in the Linux kernel before 5.16.10. The USB Gadget subsystem lacks certain validation of interface OS descriptor requests (ones with a large array index and ones associated with NULL function pointer retrieval). Memory corruption might occur.\n (CVE-2022-25258)\n\n - An issue was discovered in drivers/usb/gadget/function/rndis.c in the Linux kernel before 5.16.10. The RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command. Attackers can obtain sensitive information from kernel memory.
