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 call to deltimersync in the interrupt service routine in the i2c:pnx module that could result in a potenti...

SUSE CVE-2023-52847

In the Linux kernel, the following vulnerability has been resolved: media: bttv: fix use after free error due to btv-timeout timer There may be some a race condition between timer function bttvirqtimeout and bttvremove. The timer is setup in probe and there is no timerdelete operation in remove...

DEBIAN-CVE-2021-47512

In the Linux kernel, the following vulnerability has been resolved: net/sched: fqpie: prevent dismantle issue For some reason, fqpiedestroy did not copy working code from piedestroy and other qdiscs, thus causing elusive bug. Before calling deltimersync&q-adapttimer, we need to ensure timer will...
