CVE-2025-23134 ALSA: timer: Don't take register_mutex with copy_from/to_user()

In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: Don't take registermutex with copyfrom/touser The infamous mmaplock taken in copyfrom/touser can be often problematic when it's called inside another mutex, as they might lead to deadlocks. In the case of ALSA timer...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the ALSA timer performing a copyfrom/touser operation while holding registermutex, which could result in a...

Vulnerability of the function bt1_rom_map_copy_from(), located in the driver/mtd/maps/physmap-bt1-rom.c module. This driver provides support for accessing memory devices in Linux kernels, which can be exploited by attackers to compromise confidentiality.

The vulnerability of the bt1rommapcopyfrom function in the drivers/mtd/maps/physmap-bt1-rom.c module – the driver for accessing memory devices in Linux kernels – involves reading beyond the buffer boundaries. Exploiting this vulnerability could allow an attacker to compromise confidentiality...

SUSE CVE-2023-0459

Copyfromuser on 64-bit versions of the Linux kernel does not implement the uaccessbeginnospec allowing a user to bypass the "accessok" check and pass a kernel pointer to copyfromuser. This would allow an attacker to leak information. We recommend upgrading beyond commit...
