The vulnerability of the th1520_aon_power_update() function in the drivers/firmware/thead module, located in the Linux kernel-based firmware, allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the th1520aonpowerupdate function in the drivers/firmware/thead module, within the th1520-aon.c driver for Linux kernel patches, is related to the copying of buffers without checking the size of the input data a classic buffer overflow attack. Exploiting this vulnerability...

CVE-2025-68318

In CVE-2025-68318, the Linux kernel TH1520 ARM device shows a vulnerability where the AXI crossbar gating causes bus timeouts and possible system hang due to improper AXI clock gating. The fix sets all TH1520-AXI clocks to CLK_IS_CRITICAL (gates remain locked on reset) and migrates remaining CLK_...

Systematic Assessment of Cache Timing Vulnerabilities on RISC-V Processors

While interest in the open RISC-V instruction set architecture is growing, tools to assess the security of concrete processor implementations are lacking. There are dedicated tools and benchmarks for common microarchitectural side-channel vulnerabilities for popular processor families such as Int...
