Description Rohit Keshri 2024-02-27 16:52:33 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ice: Fix some null pointer dereference issues in ice_ptp.c

devm_kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure.

Comment 1 Rohit Keshri 2024-02-27 16:57:50 UTC 
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2266348]
Comment 3 Justin M. Forbes 2024-02-27 18:40:46 UTC 
This was introduced in 6.7 and fixed in 6.7.2/6.8-rc1. It never hit stable Fedora releases.
Comment 5 Michal Schmidt 2024-03-19 14:04:55 UTC 
Small GFP_KERNEL allocations never fail. It is the de-facto rule of the Linux kernel known as "too small to fail".
See:
https://lwn.net/Articles/964793/
  quote: "The kernel, for all practical purposes, already implements GFP_NOFAIL behavior for allocations of eight pages or less."
And older articles about the same topic:
https://lwn.net/Articles/723317/
https://lwn.net/Articles/627419/

Therefore, I don't think we should treat these missing checks as CVEs.
