This kernel-linus update is based on upstream 5.15.41 and fixes at least the following security issues: A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds memory write in the Linux kernel BPF subsystem due to the way a user loads BTF. This flaw allows a local user to crash or escalate their privileges on the system. NOTE: Mageia kernels by default prevents unprivileged users from being able to use eBPF so this would require a privileged user with CAP_SYS_ADMIN or root to be able to abuse this flaw reducing its attack space (CVE-2022-0500). 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-2022-1012). A flaw was found in the Linux kernel’s nfcmrvl_nci_unregister_dev() function. A race condition leads to a use-after-free issue when simulating the NFC device from the user space (CVE-2022-1734). A flaw was found in the Linux kernel's adjust_ptr_min_max_vals in the kernel/bpf/verifier.c function. In this flaw, a missing sanity check for *_OR_NULL pointer types that perform pointer arithmetic may cause a kernel information leak issue. NOTE: Mageia kernels by default prevents unprivileged users from being able to use eBPF so this would require a privileged user with CAP_SYS_ADMIN or root to be able to abuse this flaw reducing its attack space (CVE-2022-23222). The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state (CVE-2022-28893). Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root (CVE-2022-29581). For other upstream fixes, see the referenced changelogs.

This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation. (CVE-2021-22543)\n\n - A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds memory write in the Linux kernel's BPF subsystem due to the way a user loads BTF. This flaw allows a local user to crash or escalate their privileges on the system. (CVE-2022-0500)\n\n - A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem.\n This flaw allows a local user to cause an out-of-bounds write issue. (CVE-2022-1015)\n\n - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information. (CVE-2022-1353)\n\n - kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of the availability of pointer arithmetic via certain *_OR_NULL pointer types. (CVE-2022-23222)\n\n - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state. (CVE-2022-28893)\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - 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)\n\n - The Linux kernel before 5.17.2 mishandles seccomp permissions.

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)\n\n - Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system. (CVE-2022-1652)\n\n - An issue was discovered in the Linux Kernel from 4.18 to 4.19, an improper update of sock reference in TCP pacing can lead to memory/netns leak, which can be used by remote clients. (CVE-2022-1678)\n\n - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use after free both read or write when non synchronized between cleanup routine and firmware download routine.\n (CVE-2022-1734)\n\n - With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.\n (CVE-2022-1789)\n\n - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER.

This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)\n\n - 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. (CVE-2022-32250)\n\n - kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.
