Debian Linux Security Advisory 4698-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.
6b0461d5fdc0442553e93411732b13c0f292cb8ee0cf3b5b3b0228efca950d91Red Hat Security Advisory 2020-1493-01 - The kernel-alt packages provide the Linux kernel version 4.x. Issues addressed include buffer overflow, denial of service, heap overflow, and null pointer vulnerabilities.
f9f905afbd1c07e906b01a9b5f9efb2a071312f8ce6cf0b7ced2546f5dad629eMitchell Frank discovered that the Wi-Fi implementation in the Linux kernel when used as an access point would send IAPP location updates for stations before client authentication had completed. A physically proximate attacker could use this to cause a denial of service. It was discovered that the Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacker could use this to expose sensitive information. Various other issues were also addressed.
