Amazon Linux 2 : kernel (ALAS-2020-1440)

The version of kernel installed on the remote host is prior to 4.14.177-139.253. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1440 advisory. A flaw was found in the Linux kernel's implementation of the BFQ IO scheduler. This flaw allows a local user able ...

Linux kernel input validation error vulnerability (CNVD-2020-40610)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the execid variable in the include / linux / sched.h file in Linux kernel versions prior to 5.6.5 CID-7395ea4e65c2. An attacker can...

CVE-2020-12826

CVE-2020-12826 affects the Linux kernel before 5.6.5. The root cause is an integer overflow in exec_id (include/linux/sched.h) due to 32-bit sizing, which can allow a child process to send an arbitrary signal to a parent process in a different security domain, bypassing protection. A patched vers...

CVE-2020-12826

A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2. Because execid in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a donotifyparent protection mechanism. A child process can send an arbitrary signal to a parent...
