- Summary
- genirq/ipi: Fix NULL pointer deref in irq_data_get_affinity_mask()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
genirq/ipi: Fix NULL pointer deref in irqdatagetaffinitymask()
If ipisend{mask|single}() is called with an invalid interrupt number, all the local variables there will be NULL. ipisendverify() which is invoked from these functions does verify its 'data' parameter, resulting in a kernel oops in irqdatagetaffinitymask() as the passed NULL pointer gets dereferenced.
Add a missing NULL pointer check in ipisendverify()...
Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.
