Summary
linux, linux-aws, linux-aws-5.11, linux-azure, linux-azure-5.11, linux-gcp, linux-gcp-5.11, linux-hwe-5.11, linux-kvm, linux-oem-5.10, linux-oracle, linux-oracle-5.11, linux-raspi vulnerability
Details
It was discovered that the eBPF implementation in the Linux kernel did not properly validate the memory size of certain ring buffer operation arguments. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
