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 allows users\n with the ability to start and control a VM to read/write random pages of memory and can result in local\n 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\n memory write in the Linux kernel's BPF subsystem due to the way a user loads BTF. This flaw allows a local\n 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\n flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a\n 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\n 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\n 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\n cause privilege escalation to root.

(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\n timeouts.
