| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.8.0-rc6-std-def-alt1 #1
Description:
The vulnerability is related to a use-after-free and null-ptr-deref issue in the gtp newlink function. The gtp link ops operations structure for the subsystem must be registered after registering the gtp net ops pernet operations structure. This issue can cause a general protection fault, probably due to a non-canonical address. The vulnerability was identified by Syzkaller, which hit a 'general protection fault in gtp genl dump pdp' bug.
Recommendations:
To resolve this issue, update the Linux kernel to a version that includes the fix for the gtp newlink function. Specifically, update to a version later than 6.8.0-rc6-std-def-alt1 #1.
Note: The provided input data does not specify the exact fixed version, so it is recommended to update to the latest available version of the Linux kernel.
