CVE-2023-53470

Root has patched CVE-2023-53470 in the linux package for Root:Debian:11. Multiple fixed versions available.

In the Linux kernel, the following vulnerability has been resolved: ionic: catch failure from devlink_alloc Add a check for NULL on the alloc return. If devlink_alloc() fails and we try to use devlink_priv() on the NULL return, the kernel gets very unhappy and panics. With this fix, the driver load will still fail, but at least it won't panic the kernel.

In the Linux kernel, the following vulnerability has been resolved:

ionic: catch failure from devlink_alloc

Add a check for NULL on the alloc return. If devlink_alloc() fails and we try to use devlink_priv() on the NULL return, the kernel gets very unhappy and panics. With this fix, the driver load will still fail, but at least it won't panic the kernel.
