GFP_KERNEL may sleep, which is not allowed in this atomic context and can trigger a sleeping-from-invalid-context warning or deadlock. Pass GFP_ATOMIC so the allocation is safe under the IRQ-safe spinlock. The Linux kernel CVE team has assigned CVE-2026-89514 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/scsi/fnic/fip.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/c4ade059aaeb51fdb3f4ae71e1ea3e2019b85178 https://git.kernel.org/stable/c/d86f65aed01408613607f8fc31493f07554788f2 https://git.kernel.org/stable/c/9639c6324524ea3f934908bd51f02430000954ab
