CVE-2025-39989

The CVE-2025-39989 issue affects the Linux kernel’s x86 memory error handling (MCE) path. Root cause: a patch series changes the copy-from-user recovery flow by introducing and switching extable fixup types, notably EX_TYPE_EFAULT_REG, instead of handling EX_TYPE_UACCESS for poison found in get_u...

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...
