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 a restriction on writing BIOs to partitioned devices that is not handled correctly, which could result in a...

SUSE CVE-2025-39736

In the Linux kernel, the following vulnerability has been resolved: mm/kmemleak: avoid deadlock by moving prwarn outside kmemleaklock When netpoll is enabled, calling prwarnonce while holding kmemleaklock in mempoolalloc can cause a deadlock due to lock inversion with the netconsole subsystem. Th...

SUSE CVE-2025-39744

In the Linux kernel, the following vulnerability has been resolved: rcu: Fix rcureadunlock deadloop due to IRQ work During rcureadunlockspecial, if this happens during irqexit, we can lockup if an IPI is issued. This is because the IPI itself triggers the irqexit path causing a recursive lock up...
