Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0448 advisory.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* kernel: bpf: Incorrect verifier pruning leads to unsafe code paths being incorrectly marked as safe (CVE-2023-2163)

* kernel: use after free in unix_stream_sendpage (CVE-2023-4622)

* kernel: net/sched: sch_hfsc UAF (CVE-2023-4623)

* kernel: eBPF: insufficient stack type checks in dynptr (CVE-2023-39191)

* kernel: IGB driver inadequate buffer size for frames larger than MTU (CVE-2023-45871)

* kernel: nfp: use-after-free in area_cache_get() (CVE-2022-3545)

* kernel: null-ptr-deref vulnerabilities in sl_tx_timeout in drivers/net/slip (CVE-2022-41858)

* kernel: UAF during login when accessing the shost ipaddress (CVE-2023-2162)

* kernel: NULL pointer dereference in can_rcv_filter (CVE-2023-2166)

* kernel: Slab-out-of-bound read in compare_netdev_and_ip (CVE-2023-2176)

* kernel: use after free in vcs_read in drivers/tty/vt/vc_screen.c due to race (CVE-2023-3567)

* kernel: use-after-free in netfilter: nf_tables (CVE-2023-3777)

* kernel: use after free in nft_immediate_deactivate (CVE-2023-4015)

* kernel: A heap out-of-bounds write (CVE-2023-5717)

* hw amd: Return Address Predictor vulnerability leading to information disclosure (CVE-2023-20569)

* kernel: fbcon: out-of-sync arrays in fbcon_mode_deleted due to wrong con2fb_map assignment (CVE-2023-38409)

* kernel: use-after-free in l2cap_sock_release in net/bluetooth/l2cap_sock.c (CVE-2023-40283)

* kernel: SEV-ES local priv escalation (CVE-2023-46813)

* kernel: use-after-free in smb2_is_status_io_timeout() (CVE-2023-1192)

* kernel: NULL pointer dereference in dpll_pin_parent_pin_set() in drivers/dpll/dpll_netlink.c (CVE-2023-6679)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* sev-guest is not loaded automatically in the guest kernel when sev-snp is enabled (BZ#2218934)

* Cgroups v2: Current interface to disable cpu load balancing not compatible with kubernetes cgroup hierarchy (BZ#2238754)

* WPC ice driver misc irq not getting generated for a interface. (BZ#2245881)

* RHEL9.0 - s390/qeth: NET2016 - fix use-after-free in HSCI (BZ#2247798)

* pNFS/filelayout: treat GETDEVICEINFO errors as layout failure (BZ#2249557)

* cifs: fix dentry lookups in directory handle cache (BZ#2249558)

* Performance regression with random 2 KiB writes to ext4 filesystem with 4 KiB filesystem blocks (BZ#2249685)

* kernel.spec: Fix UKI naming to comply with BLS (BZ#2254546)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL kernel package based on the guidance in RHSA-2024:0448.
