ALSA-2023:7549 — Important: kernel security and bug fix update

Affected: AlmaLinux:8: bpftool, AlmaLinux:8: kernel, AlmaLinux:8: kernel-abi-stablelists, AlmaLinux:8: kernel-core, AlmaLinux:8: kernel-cross-headers, AlmaLinux:8: kernel-debug, AlmaLinux:8: kernel-debug-core, AlmaLinux:8: kernel-debug-devel, AlmaLinux:8: kernel-debug-modules, AlmaLinux:8: kernel-debug-modules-extra and 14 more

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* kernel: bpf: Incorrect verifier pruning leads to unsafe code paths being incorrectly marked as safe (CVE-2023-2163) * kernel: tun: bugs for oversize packet when napi frags enabled in tun_napi_alloc_frags (CVE-2023-3812) * kernel: use after free in nvmet_tcp_free_crypto in NVMe (CVE-2023-5178) * kernel: use-after-free due to race condition occurring in dvb_register_device() (CVE-2022-45884) * kernel: use-after-free due to race condition occurring in dvb_net.c (CVE-2022-45886) * kernel: use-after-free due to race condition occurring in dvb_ca_en50221.c (CVE-2022-45919) * kernel: use-after-free in smb2_is_status_io_timeout() (CVE-2023-1192)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es): * Fix max integer mmu_invalidate_seq hanging vCPU (ALBZ#445) * Random delay receiving packets after bringing up VLAN on top of VF with vf-vlan-pruning enabled (BZ#2240750) * bpf_jit_limit hit again (BZ#2243011) * HPE Edgeline 920t resets during kdump context when ice driver is loaded and when system is booted with intel_iommu=on iommu=pt (BZ#2244625)

OESA-2023-1841 — kernel security update

Affected: openEuler:20.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvbdev.c has a use-after-free, related to dvb_register_device dynamically allocating fops.(CVE-2022-45884) Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2023-35823. Reason: This candidate is a reservation duplicate of CVE-2023-35823. Notes: All CVE users should reference CVE-2023-35823 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage.(CVE-2023-3327) A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a use-after-free issue, potentially leading to a denial of service or privilege escalation.(CVE-2023-39198) A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control) component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling pointer that can cause a use-after-free. W…
