Title
firmware: arm_ffa: Fix NULL dereference in ffa_partition_info_get()
Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_ffa: Fix NULL dereference in ffa_partition_info_get()
ffa_partition_info_get() passes uuid_str directly to uuid_parse()
without a NULL check. When a caller passes NULL, uuid_parse() ->
__uuid_parse() -> uuid_is_valid() dereferences the pointer, causing
a kernel panic:
| Unable to handle kernel NULL pointer dereference at virtual address
| 0000000000000040
| pc : uuid_parse+0x40/0xac
| lr : ffa_partition_info_get+0x1c/0x94 [arm_ffa]
Add a NULL guard before uuid_parse() so a NULL argument returns
-ENODEV instead of crashing. Callers are expected to always supply
a valid partition UUID, so NULL is not a supported input.
Severity
No CVSS data available.
