USN-5728-3 linux-gcp-5.4 vulnerabilities

Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2022-427...

kernel: x86/speculation: Fill RSB on vmexit for IBRS

In the Linux kernel, the following vulnerability has been resolved: x86/speculation: Fill RSB on vmexit for IBRS Prevent RSB underflow/poisoning attacks with RSB. While at it, add a bunch of comments to attempt to document the current state of tribal knowledge about RSB attacks and what exactly i...
