CVE-2022-49466

CVE-2022-49466 affects the Linux kernel regulator: scmi subsystem. The root cause is a refcount leak in scmi_regulator_probe due to of_find_node_by_name() returning a node pointer with an incremented refcount; the patch adds a call to of_node_put() to release the node when done. This fix prevents...

CVE-2022-49190

CVE-2022-49190 affects the Linux kernel (kernel/resource). Root cause: boot memory allocated via alloc_resource() may be leaked if callers use kfree directly, causing a kernel BUG; remediation leaks only a few bytes to avoid patching every call site. A fix was applied in the kernel (commit ebff7d...
