CVE-2026-68444: firmware: arm_ffa: Fix NULL dereference in ffa_partition_info_get()

—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 12a42c610e4432e7708cc48d607e5903fffe0aad, 7201e56e52d18abf4cd0a2fee45daf9dc08b5b97, 7dfb020e3048411fbca91e9ad6174da9a2d3e2b3; azl3 kernel 6.6.143.1-1 on Azure Linux 3.0 6.6.150.1-1.

Low priority for now. Upgrade to Linux Linux 12a42c610e4432e7708cc48d607e5903fffe0aad, 7201e56e52d18abf4cd0a2fee45daf9dc08b5b97, 7dfb020e3048411fbca91e9ad6174da9a2d3e2b3; azl3 kernel 6.6.143.1-1 on Azure Linux 3.0 6.6.150.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
