CVE-2021-47486

CVE-2021-47486 affects the Linux kernel’s RISC-V BPF JIT: when NR_JIT_ITERATIONS is reached and jit_data->header is NULL, bpf_jit_binary_free() dereferences a NULL and can crash. The fix is a NULL-argument check before calling bpf_jit_binary_free(), per the provided description. Public details...

In the Linux kernel, the following vulnerability has been resolved: riscv: VMAPSTACK overflow detection thread-safe commit 31da94c25aea "riscv: add VMAPSTACK overflow detection" added support for CONFIGVMAPSTACK. If overflow is detected, CPU switches to shadowstack temporarily before switching...

CVE-2023-52839 drivers: perf: Do not broadcast to other cpus when starting a counter

In the Linux kernel, the following vulnerability has been resolved: drivers: perf: Do not broadcast to other cpus when starting a counter This command: $ perf record -e cycles:k -e instructions:k -c 10000 -m 64M dd if=/dev/zero of=/dev/null count=1000 gives rise to this kernel warning: 444.364395...

CVE-2023-52761

The CVE-2023-52761 entry concerns a Linux kernel vulnerability on riscv where VMAP_STACK overflow detection was made thread-safe. The patch (commit 31da94c25aea) adds support for CONFIG_VMAP_STACK and optimizes overflow handling by directly using the per-cpu overflow_stack, removing the shadow_st...

CVE-2021-47414

Summary: CVE-2021-47414 concerns a Linux kernel vulnerability on RISCV (SiFive HiFive Unmatched) where ftrace patching may trigger an illegal instruction due to icache/dcache synchronization across CPUs. The root cause is that icache of the current CPU is not flushed before other CPUs are asked t...

CVE-2024-35987

A vulnerability was found in the Linux kernel that affects 64-bit No Memory Management Unit NOMMU systems. The issue arose from a change that allowed using RAM below the kernel load address, which conflicts with the fixed PAGEOFFSET in NOMMU systems. This leads to memory initialization errors and...

CVE-2024-35873

A vulnerability was found in the Linux kernel, affecting the RISC-V architecture. It arises during the restoration of the vector state in the rtsigreturn syscall after a signal handler is executed. The bug occurs when the live vector state is discarded and marked as "dirty," leading to corruption...
