Description

Updated kernel packages fix security vulnerabilities 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. For other upstream fixes in this update, see the referenced changelogs.
