The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012) * kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-32250) 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): * Softirq hrtimers are being placed on the per-CPU softirq clocks on isolcpu’s. (BZ#2090484) * enable/disable multiqueues repeatedly while ping local host, guest kernel panic (BZ#2093416) * Backport kernel audit enhancements and fixes from v5.13-rc1 to v5.16-rc6 (BZ#2095434) * blk_update_request: I/O error, dev nvme0n3, during xfs creation (BZ#2100150) * SCSI updates for AlmaLinux 8.7 (BZ#2100254) * Kernel bug on mm/slub.c:314 (BZ#2102251) * Implement new tc action for check_pkt_len (BZ#2102333) * too long timeout value with TIME_WAIT status of conntrack entry (BZ#2104002) * Connectx6-DX, mlx5 , backport 087032ee7021 ("net/mlx5e: TC, Fix ct_clear overwriting ct action metadata") (BZ#2104012) * mlx5: Software steering memory allocation failure, netperf TCP_CRR with ct(). (BZ#2104013) * tcp: request_sock leak in Calico OCP (BZ#2104670)

net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free.

ICSA-23-166-11 — Siemens SIMATIC S7-1500 TM MFP Linux Kernel

json-c through 0.14 has an integer overflow and out-of-bounds write via a large JSON file, as demonstrated by printbuf_memappend. A memory overflow vulnerability was found in the Linux kernel’s ipc functionality of the memcg subsystem, in the way a user calls the semget function multiple times, creating semaphores. This flaw allows a local user to starve the resources, causing a denial of service. The highest threat from this vulnerability is to system availability. A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. This vulnerability is similar to the previous CVE-2018-13405 and adds the missed fix for the XFS. When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds. In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered, leading to a move_data_page NULL pointer dereference. A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root (host) user-level application to crash the host kernel by creating a confidential guest VM inst…

OESA-2022-1725 — 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):

In lg_probe and related functions of hid-lg.c and other USB HID files, there is a possible out of bounds read due to improper input validation. This could lead to local information disclosure if a malicious USB HID device were plugged in, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-188677105References: Upstream kernel(CVE-2022-20132) In lock_sock_nested of sock.c, there is a possible use after free due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-174846563References: Upstream kernel(CVE-2022-20154)

A use-after-free vulnerability was found in the Linux kernel s Netfilter subsystem in net/netfilter/nf_tables_api.c. This flaw allows a local attacker with user access to cause a privilege escalation issue.(CVE-2022-1966)

The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are used.(CVE-2022-32296)

An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point registers. (CVE-2022-32981)
