CVE-2022-50615

In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Fix reference count leak in snruncoremmiomap pcigetdevice will increase the reference count for the returned pcidev, so snruncoregetmcdev will return a pcidev with its reference count increased. We need to...

CVE-2022-50659

A reference count leak was found in the AMD Geode hardware random number generator driver in the Linux kernel. When breaking out of the foreachpcidev loop early, the driver fails to call pcidevput to decrement the PCI device reference count, leading to a memory leak that could exhaust system...

CVE-2022-50661

A memory leak flaw was found in the Linux kernel's seccomp subsystem. When a process using seccomp filters is interrupted by a fatal signal during clone, the seccompfilter structure and associated BPF program memory are not properly freed. This occurs because copyseccomp is called before the...

SUSE CVE-2022-50659

In the Linux kernel, the following vulnerability has been resolved: hwrng: geode - Fix PCI device refcount leak foreachpcidev is implemented by pcigetdevice. The comment of pcigetdevice says that it will increase the reference count for the returned pcidev and also decrease the reference count fo...
