"The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2022:3585-1 advisory.

  - A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled.
    This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a
    kernel oops condition that results in a denial of service. (CVE-2022-1263)

  - kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation
    (CVE-2022-2586)

  - A NULL pointer dereference flaw in diFree in fs/jfs/inode.c in Journaled File System (JFS)in the Linux
    kernel. This could allow a local attacker to crash the system or leak kernel internal information.
    (CVE-2022-3202)

  - A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers
    em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system
    or potentially escalate their privileges on the system. (CVE-2022-3239)

  - A race condition flaw was found in the Linux kernel sound subsystem due to improper locking. It could lead
    to a NULL pointer dereference while handling the SNDCTL_DSP_SYNC ioctl. A privileged local user (root or
    member of the audio group) could use this flaw to crash the system, resulting in a denial of service
    condition (CVE-2022-3303)

  - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users
    can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED
    situations. (CVE-2022-39189)

  - In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused
    by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. (CVE-2022-41218)

  - drivers/char/pcmcia/synclink_cs.c in the Linux kernel through 5.19.12 has a race condition and resultant
    use-after-free if a physically proximate attacker removes a PCMCIA device while calling ioctl, aka a race
    condition between mgslpc_ioctl and mgslpc_detach. (CVE-2022-41848)

  - drivers/video/fbdev/smscufx.c in the Linux kernel through 5.19.12 has a race condition and resultant use-
    after-free if a physically proximate attacker removes a USB device while calling open(), aka a race
    condition between ufx_ops_open and ufx_usb_disconnect. (CVE-2022-41849)

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