The bug\nallows to build several exploit primitives such as kernel address\ninformation leak, arbitrary execution, etc.\n\n#### Notes\n\nAuthor| Note \n---|--- \n[alexmurray](<https://launchpad.net/~alexmurray>) | Ubuntu kernels enable SECURITY_PERF_EVENTS_RESTRICT which sets kernel.perf_event_paranoid &gt;= 3 and so disables unprivileged users from using perf by default. As such in their default configuration, Ubuntu kernels are not able to be exploited by this flaw to achieve local privilege escalation.\n", "published": "2022-05-20T00:00:00", "modified":

The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. (CVE-2022-1729)\n\n - In lock_sock_nested of sock.c, there is a possible use after free due to a race condition.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1798 advisory.\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 - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.\n This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)\n\n - A NULL pointer dereference flaw was found in the Linux kernel's X.25 set of standardized network protocols functionality in the way a user terminates their session using a simulated Ethernet card and continued usage of this connection. This flaw allows a local user to crash the system. (CVE-2022-1516)\n\n - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. (CVE-2022-1729)\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.
