ALSA-2022:7444 — Moderate: 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):

* off-path attacker may inject data or terminate victim's TCP session (CVE-2020-36516) * Race condition in VT_RESIZEX ioctl when vc_cons[i].d is already NULL leading to NULL pointer dereference (CVE-2020-36558) * use-after-free vulnerability in function sco_sock_sendmsg() (CVE-2021-3640) * Memory leak for large arguments in video_usercopy function in drivers/media/v4l2-core/v4l2-ioctl.c (CVE-2021-30002) * smb2_ioctl_query_info NULL Pointer Dereference (CVE-2022-0168) * NULL pointer dereference in udf_expand_file_adinicbdue() during writeback (CVE-2022-0617) * swiotlb information leak with DMA_FROM_DEVICE (CVE-2022-0854) * Uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM (CVE-2022-1016) * Race condition in snd_pcm_hw_free leading to use-after-free (CVE-2022-1048) * use-after-free in tc_new_tfilter() in net/sched/cls_api.c (CVE-2022-1055) * use-after-free and memory errors in ext4 when mounting and operating on a corrupted image (CVE-2022-1184) * NULL pointer dereference in x86_emulate_insn may lead to DoS (CVE-2022-1852) * buffer overflow in nft_set_desc_concat_parse() (CVE-2022-2078) * nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586) * openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size() (CVE-202…

OESA-2022-1691 — 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): Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access.(CVE-2022-0002) In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race condition perhaps can only be exploited infrequently.(CVE-2022-29582) A use-after-free vulnerability was found in the Linux kernel in drivers/net/hamradio. This flaw allows a local attacker with a user privilege to cause a denial of service (DOS) when the mkiss or sixpack device is detached and reclaim resources early.(CVE-2022-1195) In mmc_blk_read_single of block.c, there is a possible way to read kernel heap memory due to uninitialized data. This could lead to local information disclosure if reading from an SD card that triggers errors, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-216481035References: Upstream kernel(CVE-2022-20008) Due to the small table perturb size, a memory leak flaw was found in the Linux kernel’s TCP source port generation algorithm in the net/ipv4/tcp.c function. This flaw allows an attacker to leak information and may cause a denial of service.(CVE-2022…
