ALSA-2023:2148 — Important: kernel-rt security and bug fix update

Affected: AlmaLinux:9: kernel-rt, AlmaLinux:9: kernel-rt-core, AlmaLinux:9: kernel-rt-debug, AlmaLinux:9: kernel-rt-debug-core, AlmaLinux:9: kernel-rt-debug-devel, AlmaLinux:9: kernel-rt-debug-kvm, AlmaLinux:9: kernel-rt-debug-modules, AlmaLinux:9: kernel-rt-debug-modules-core, AlmaLinux:9: kernel-rt-debug-modules-extra, AlmaLinux:9: kernel-rt-devel and 4 more

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

Security Fix(es):

* use-after-free in l2cap_connect and l2cap_le_connect_req in net/bluetooth/l2cap_core.c (CVE-2022-42896) * net/ulp: use-after-free in listening ULP sockets (CVE-2023-0461) * hw: cpu: AMD CPUs may transiently execute beyond unconditional direct branch (CVE-2021-26341) * malicious data for FBIOPUT_VSCREENINFO ioctl may cause OOB write memory (CVE-2021-33655) * possible race condition in drivers/tty/tty_buffers.c (CVE-2022-1462) * KVM: NULL pointer dereference in kvm_mmu_invpcid_gva (CVE-2022-1789) * use-after-free in free_pipe_info() could lead to privilege escalation (CVE-2022-1882) * KVM: nVMX: missing IBPB when exiting from nested guest can lead to Spectre v2 attacks (CVE-2022-2196) * netfilter: nf_conntrack_irc message handling issue (CVE-2022-2663) * race condition in xfrm_probe_algs can lead to OOB read/write (CVE-2022-3028) * out-of-bounds read in fib_nh_match of the file net/ipv4/fib_semantics.c (CVE-2022-3435) * race condition in hugetlb_no_page() in mm/hugetlb.c (CVE-2022-3522) * memory leak in ipv6_renew_options() (CVE-2022-3524) * data races around icsk->icsk_af_ops in do_ipv6_setsockopt (CVE-2022-3566) * data races around sk->sk_prot (CVE-2022-3567) * memory leak in l2cap_recv_acldata of the file net/bluetooth/l2cap_core.c (CVE-2022-3619) * denial of service in follow_page_pte in mm/gup.c due to poisone…

network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further processing to nevertheless be freed.

OESA-2022-1774 — kernel security update

Affected: openEuler:20.03-LTS-SP1: kernel, openEuler:20.03-LTS-SP3: kernel, openEuler:22.03-LTS: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that allow attackers to crash linux kernel without any privileges.(CVE-2022-2318) 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) Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the related lock held, resulting in a small race window, which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS) of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory pages.(CVE-2022-33744) Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device frontends don't zero memor…
