CVE-2024-38667

CVE-2024-38667 affects the Linux kernel on RISC‑V: secondary idle threads can have their top‑of‑stack overlap with pt_regs, risking corruption of pt_regs and potentially saving/restoring a non‑existent V context. The issue mirrors a fix for the primary hart and was not propagated to secondary har...

In the Linux kernel, the following vulnerability has been resolved: riscv: Flush current cpu icache before other cpus On SiFive Unmatched, I recently fell onto the following BUG when booting: 0.000000 ftrace: allocating 36610 entries in 144 pages 0.000000 Oops - illegal instruction 1 0.000000...

The vulnerability of the add_relocation_to_accumulate() function in the module management subsystem of the riscv platform’s Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the addrelocationtoaccumulate function in the arch/riscv/kernel/module.c file, part of the Linux kernel’s module management subsystem, is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...
