Amazon Linux 2 Security Advisory: ALAS-2022-1793
Advisory Release Date: 2022-05-04 01:01 Pacific
Advisory Updated Date: 2022-05-05 14:02 Pacific
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)
mcba_usb_start_xmit in drivers/net/can/usb/mcba_usb.c in the Linux kernel through 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 attacker to create a memory leak and corrupt the underlying data structure by calling free more than once. (CVE-2022-28390)
Affected Packages:
kernel
Issue Correction:
Run yum update kernel to update your system.
