ALSA-2023:2736 — Important: kernel-rt security and bug fix update

Affected: AlmaLinux:8: kernel-rt, AlmaLinux:8: kernel-rt-core, AlmaLinux:8: kernel-rt-debug, AlmaLinux:8: kernel-rt-debug-core, AlmaLinux:8: kernel-rt-debug-devel, AlmaLinux:8: kernel-rt-debug-kvm, AlmaLinux:8: kernel-rt-debug-modules, AlmaLinux:8: kernel-rt-debug-modules-extra, AlmaLinux:8: kernel-rt-devel, AlmaLinux:8: kernel-rt-kvm and 2 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 caused by l2cap_reassemble_sdu() in net/bluetooth/l2cap_core.c (CVE-2022-3564) * 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) * when setting font with malicious data by ioctl PIO_FONT, kernel will write memory out of bounds (CVE-2021-33656) * possible race condition in drivers/tty/tty_buffers.c (CVE-2022-1462) * use-after-free in ath9k_htc_probe_device() could cause an escalation of privileges (CVE-2022-1679) * KVM: NULL pointer dereference in kvm_mmu_invpcid_gva (CVE-2022-1789) * 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) * media: em28xx: initialize refcount before kref_get (CVE-2022-3239) * 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/bluetoo…

OESA-2023-1215 — kernel security update

Affected: openEuler:20.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): A race problem was found in fs/proc/task_mmu.c in the memory management sub-component in the Linux kernel. This issue may allow a local attacker with user privilege to cause a denial of service.(CVE-2023-1582) A use-after-free flaw was found in btrfs_search_slot in fs/btrfs/ctree.c in btrfs in the Linux Kernel.This flaw allows an attacker to crash the system and possibly cause a kernel information lea(CVE-2023-1611) A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it can be further used to defeat existing kernel protection mechanisms.(CVE-2021-3923) A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of the CPU similar to the speculative execution behavior kind of attacks.(CVE-2023-1637) A flaw use after free in the Linux kernel Xircom 16-bit PCMCIA (PC-card) Ethernet driver was found.A local user could use this flaw to crash the system or potentially escalate their privileges on the system.(CVE…
