DEBIAN-CVE-2026-97587
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...

Linux Kernel Security Vulnerabilities
The Linux kernel version 5.18 contains a security vulnerability. This vulnerability arises from the use of a counter mask that stores a single unsigned long value. By iteratively using RISCVMAXCOUNTERS 64, data outside the object boundary can be read on the RV32 architecture, potentially leading ...
CVE-2025-40122: Undefined Security Weakness
