CVE-2023-0179

The Linux Kernel, the operating system core itself.

Security Fix(es):

A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution.(CVE-2023-0179)

atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results).(CVE-2023-23455)

cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results).(CVE-2023-23454)

Bug Fix(es):

• kernel-rt: update RT source tree to the latest AlmaLinux-9.1.z2 Batch (BZ#2160463)

Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel did not properly handle VLAN headers in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2023-0179)

It was discovered that the Upper Level Protocol (ULP) subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2023-0461)

This kernel update is based on upstream 5.15.88 and fixes atleast the following security issues:

A use-after-free flaw was found in the Linux kernel’s SGI GRU driver in the way the first gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially escalate their privileges on the system (CVE-2022-3424).

A vulnerability in the function btf_dump_name_dups of the file tools/lib/bpf/ btf_dump.c of the component libbpf. This flaw allows a manipulation that may lea to a use-after-free issue (CVE-2022-3534).

A vulnerability was found in area_cache_get in drivers/net/ethernet/ netronome/nfp/nfpcore/nfp_cppcore.c in the Netronome Flow Processor (NFP) driver in the Linux kernel. This flaw allows a manipulation that may lead to a use-after-free issue (CVE-2022-3545).

An out-of-bounds memory write vulnerability was found in the Linux kernel vmwgfx driver in vmw_kms_cursor_snoop due to a missing check of a memcpy length. This flaw allows a local, unprivileged attacker with access to either the /dev/dri/card0 or /dev/dri/rendererD128 and able to issue an ioctl() on the resulting file descriptor, to crash the system, causing a denial of service (CVE-2022-36280).

A use-after-free flaw was found in the Linux kernel’s dvb-core subsystem (DVB API used by Digital TV devices) in how a user physically removed a USB device (such as a DVB demultiplexer device) while running malicious code. This flaw allows a local user to crash or potentially escalate their privileges on the system (CVE-2022-41218).

An issue was discovered in the Linux kernel through 6.0.10. l2cap_config_req in net/bluetooth/l2cap_core.c has an integer wraparound via L2CAP_CONF_REQ packets (CVE-2022-45934).

In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands. This affects qdisc_graft in net/sched/sch_api.c (CVE-2022-47929).

A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution (CVE-2023-0179).

A vulnerability in the kernel ksmbd allows a remote attacker to perform a denial of service (DoS) attack. The vulnerability exists due to a boundary error within the ksmbd_decode_ntlmssp_auth_blob() function in ksmbd when handling NTLMv2 authentication. A remote attacker can send specially crafted data to ksmbd, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack (CVE-2023-0210).

ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF (CVE-2023-0266).

cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (CVE-2023-23454).

atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (CVE-2023-23455).

Other fixes in this update:

• fixes broken sound on Intel Tiger Lake systems (regression in kernel 5.15.82 released in MGASA-2022-0477 (mga #31319).
• xtables-addons have been updated to 3.23.

This kernel update is based on upstream 5.15.98 and fixes atleast the following security issues:

A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can execute code on an indirect branch on the host machine (CVE-2022-2196).

A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card system resource overload, causing a fail in the intel_gvt_dma_map_guest_page function. This issue could allow a local user to crash the system (CVE-2022-3707).

A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service (CVE-2022-4129).

A use-after-free flaw caused by a race among the superblock operations in the gadgetfs Linux driver was found. It could be triggered by yanking out a device that is running the gadgetfs side (CVE-2022-4382).

A flaw NULL Pointer Dereference in the Linux kernel NTFS3 driver function attr_punch_hole() was found. A local user could use this flaw to crash the system (CVE-2022-4842).

When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch potentially resulting in information disclosure (CVE-2022-27672).

A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution (CVE-2023-0179).

A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network subcomponent in the Linux kernel. This flaw causes the system to crash (CVE-2023-0394).

A memory corruption flaw was found in the Linux kernel’s human interface device (HID) subsystem in how a user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their privileges on the system (CVE-2023-1073).

A memory leak flaw was found in the Linux kernel's Stream Control Transmission Protocol. This issue may occur when a user starts a malicious networking service and someone connects to this service. This could allow a local user to starve resources, causing a denial of service (CVE-2023-1074).

rds: rds_rm_zerocopy_callback() use list_first_entry() (CVE-2023-1078).

An integer overflow flaw was found in the Linux kernel’s wireless RNDIS USB device driver in how a user installs a malicious USB device. This flaw allows a local user to crash or potentially escalate their privileges on the system (CVE-2023-23559).

There is a double free in net/mpls/af_mpls.c upon an allocation failure (for registering the sysctl table under a new location) during the renaming of a device (CVE-2023-26545).
