CVE-2022-1729

Vulnerability Summary

A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE. This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854) A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write(). This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation. (CVE-2022-1011) 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) 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) perf: Fix sys_perf_event_open() race against self (CVE-2022-1729) mcba_usb_start_xmit in drivers/net/can/usb/mcba_usb.c in the Linux kernel up to and including 5.17.1 has a double free. (CVE-2022-28389) A double-free flaw was found in the Linux kernel in the ems_usb_start_xmit function. This flaw allows an malicious user to create a memory leak and corrupt the underlying data structure by calling free more than once. (CVE-2022-28390) Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local malicious user 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) The Linux kernel prior to 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows malicious users to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)
