CVE-2026-97587

The Linux kernel contained a vulnerability in the perf subsystem affecting RISC-V architectures. The issue stemmed from the available-counter mask being stored as a single unsigned long , while the iteration process used RISCV_MAX_COUNTERS (64). On RV32 systems, this caused the kernel to read pas...

EUVD-2026-86895

In the Linux kernel, the following vulnerability has been resolved: perf: RISC-V: store available counter mask as bitmap The available-counter mask was a single unsigned long, but iteration uses RISCVMAXCOUNTERS, which is 64. On RV32 that reads past the object. Filling with an unsigned-long bit a...
