CVE-2026-11985

On the Zephyr ARM port, enabling the hardware FPU CONFIGFPU forces the "Floating point ABI" choice, which defaults to CONFIGFPHARDABI. Both FPHARDABI and FPSOFTABI permit the compiler to emit hardware FP instructions in any function, even code that never uses floating-point types. However, the...

CVE-2026-11985 Cross-thread FPU register leak on ARM when FPU enabled without register sharing

On the Zephyr ARM port, enabling the hardware FPU CONFIGFPU forces the "Floating point ABI" choice, which defaults to CONFIGFPHARDABI. Both FPHARDABI and FPSOFTABI permit the compiler to emit hardware FP instructions in any function, even code that never uses floating-point types. However, the...

CVE-2026-7007 Division by zero in Zephyr ext2 superblock parsing allows DoS via crafted filesystem image

The Zephyr ext2 file system validates the on-disk superblock in ext2verifydisksuperblock subsys/fs/ext2/ext2impl.c before completing a mount. The validator checked the magic number, block size, revision and feature flags, but did not verify that the on-disk fields sblockspergroup and...

Astra Linux – Vulnerability in Linux, Linux 5.10

Certain Arm Cortex and Neoverse processors, as of 2022-03-08, do not properly prevent cache speculation, also known as Spectre-BHB. Attackers can exploit the shared branch history in the Branch History Buffer BHB to influence mispredicted branches. As a result, cache allocation may allow attacker...
