RHEL 9 : kernel-rt (RHSA-2024:1306)

high Nessus Plugin ID 192035

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1306 advisory.

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

* memcg does not limit the number of POSIX file locks allowing memory exhaustion (CVE-2022-0480)

* vmwgfx: NULL pointer dereference in vmw_cmd_dx_define_query (CVE-2022-38096)

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

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

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

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

* UAF in nftables when nft_set_lookup_global triggered after handling named and anonymous sets in batch requests (CVE-2023-3390)

* out-of-bounds access in relay_file_read (CVE-2023-3268)

* vmxnet3: NULL pointer dereference in vmxnet3_rq_cleanup() (CVE-2023-4459)

* Gather Data Sampling (GDS) side channel vulnerability (CVE-2022-40982,Downfall)

* net/sched: cls_u32 component reference counter leak if tcf_change_indev() fails (CVE-2023-3609)

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

* Race Condition leading to UAF in Unix Socket could happen in sk_receive_queue ()

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

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

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

* A heap out-of-bounds write when function perf_read_group is called and sibling_list is smaller than its child's sibling_list (CVE-2023-5717)

* ktls overwrites readonly memory pages when using function splice with a ktls socket as destination (CVE-2024-0646)

* use-after-free in IPv4 IGMP (CVE-2023-6932)

* GSM multiplexing race condition leads to privilege escalation (CVE-2023-6546,ZDI-CAN-20527)

* refcount leak in ctnetlink_create_conntrack() (CVE-2023-7192)
