SUSE CVE-2019-11479

Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kerne...

SUSE CVE-2021-3444

The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known to be 0. A local attacker with the ability to load bpf programs could use this gain out-of-bounds reads in kernel memory leading to information disclosure kernel...

SUSE CVE-2021-3491

The iouring subsystem in the Linux kernel allowed the MAXRWCOUNT limit to be bypassed in the PROVIDEBUFFERS operation, which led to negative values being usedin memrw when reading /proc//mem. This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was...
