In the Linux kernel, the following vulnerability has been resolved:
lib/string_helpers: fix not adding strarray to device's resource list
Add allocated strarray to device's resource list. This is a must to
automatically release strarray when the device disappears.
Without this fix we have a memory leak in the few drivers which use
devm_kasprintf_strarray().

CVE-2022-49403 is a vulnerability in the Linux kernel's handling of IPv6 networking, specifically in the Segment Routing feature. The issue stems from a logic error during cleanup, where certain network route objects can be freed (deleted from memory) more than once. This type of mistake is known as a use-after-free bug and can lead to unpredictable behavior
