The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-9761 advisory.

  - In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum     address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP     platforms. This is related to a capability check for the wrong task. (CVE-2019-9213)

  - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the     hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session     or terminate that session. (CVE-2020-36516)

  - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds. (CVE-2021-33655)

  - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.
    (CVE-2021-33656)

  - A race condition in the Linux kernel before 5.6.2 between the VT_DISALLOCATE ioctl and closing/opening of     ttys could lead to a use-after-free. (CVE-2020-36557)

  - A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer     dereference and general protection fault. (CVE-2020-36558)

  - 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)

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

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-9830 advisory.

  - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation     (CVE-2022-2588)

  - A flaw in net_rds_alloc_sgs() in Oracle Linux kernels allows unprivileged local users to crash the     machine. CVSS 3.1 Base Score 6.2 (Availability impacts). CVSS Vector     (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) (CVE-2022-21385)

  - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462) (CVE-2022-2586)

  - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init     (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different     vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an     unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data     in net/netfilter/nf_tables_api.c. (CVE-2022-34918)

  - A use-after-free flaw was found in the Linux kernel's POSIX CPU timers functionality in the way a user     creates and then deletes the timer in the non-leader thread of the program. This flaw allows a local user     to crash or potentially escalate their privileges on the system. (CVE-2022-2585) (CVE-2022-2585)

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

The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2022-9788 advisory.

  - A flaw in net_rds_alloc_sgs() in Oracle Linux kernels allows unprivileged local users to crash the     machine. CVSS 3.1 Base Score 6.2 (Availability impacts). CVSS Vector     (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) (CVE-2022-21385)

The remote Oracle Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-9828 advisory.

  - A use-after-free vulnerability was found in drm_lease_held in drivers/gpu/drm/drm_lease.c in the Linux     kernel due to a race problem. This flaw allows a local user privilege attacker to cause a denial of     service (DoS) or a kernel information leak. (CVE-2022-1280)

  - A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large     shared memory segment counts which could lead to resource exhaustion and DoS. (CVE-2021-3669)

  - A flaw in net_rds_alloc_sgs() in Oracle Linux kernels allows unprivileged local users to crash the     machine. CVSS 3.1 Base Score 6.2 (Availability impacts). CVSS Vector     (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) (CVE-2022-21385)

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