CVE-2022-50868

The CVE-2022-50868 issue is in the Linux kernel hwrng: amd driver, where for_each_pci_dev() (implemented via pci_get_device()) can leak PCI device references. The root cause is a missing pci_dev_put() on the normal and error paths when breaking out of for_each_pci_dev() with a non-NULL pdev, lead...

CVE-2022-50855

The CVE-2022-50855 entry concerns a Linux kernel issue where the BPF LSM program attached via bpf_prog_attach to cgroups could leak because the refcnt wasn’t decremented when the validation rejected the attach.
