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...

CVE-2023-52761

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...

USN-6820-1 linux, linux-gcp, linux-gcp-5.15, linux-lowlatency, linux-lowlatency-hwe-5.15, linux-xilinx-zynqmp vulnerabilities

It was discovered that the ATA over Ethernet AoE driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. CVE-2023-6270 It was discovered that the Atheros 802.11ac...

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,...
