CVE-2026-46253

A flaw was found in the Linux kernel's pstore/ram component. This vulnerability, a heap buffer overflow, occurs when the system attempts to save old persistent RAM logs and the buffer size changes, leading to an out-of-bounds write. While the conditions for exploitation are extremely difficult to...

CVE-2026-46253

In Linux kernel pstore/ram, CVE-2026-46253, the vulnerability is a heap buffer overflow during persistent_ram_save_old(). If the buffer size has grown since the first allocation, the code updates old_log_size to the new size and then copies with memcpy_fromio(), risking an out-of-bounds write (an...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the pstore ram module not properly updating the oldlogsize when it calls the persistentramsaveold...

PT-2026-46016

In the Linux kernel, the following vulnerability has been resolved: pstore/ram: Check the start of empty przs during initialization. After the commit 30696378f68a “pstore/ram: Do not treat empty buffers as valid”, initialization would assume that the prz was valid after determining that buffersiz...

CVE-2026-43124

A flaw was found in the Linux kernel's pstore ramcore component. A local attacker could exploit a vulnerability where the persistentrambuffermap function incorrectly returns success even when the underlying vmap memory mapping operation fails. This occurs if a non-zero offset is used, leading to...
