"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2022:819 advisory.

  - 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)

  - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the
    way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or
    escalate their privileges on the system. (CVE-2022-0330)

  - A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends
    a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
    This flaw allows a remote user to crash the system or possibly escalate their privileges if they have
    access to the TIPC network. (CVE-2022-0435)

  - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the
    kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups
    v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
    (CVE-2022-0492)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
