kernel: netfilter: nf_tables: fix underflow in chain reference counter
A flaw was found in the Linux kernel's netfilter nftables component. During set element addition, an error path incorrectly decrements the chain reference counter twice. This reference count underflow could potentially lead to a use-after-free condition when the chain is subsequently freed while...
kernel: media: dvbdev: adopts refcnt to avoid UAF
In the Linux kernel, the following vulnerability has been resolved: media: dvbdev: adopts refcnt to avoid UAF dvbunregisterdevice is known that prone to use-after-free. That is, the cleanup from dvbunregisterdevice releases the dvbdevice even if there are pointers stored in file-privatedata still...
UBUNTU-CVE-2021-47358
In the Linux kernel, the following vulnerability has been resolved: staging: greybus: uart: fix tty use after free User space can hold a tty open indefinitely and tty drivers must not release the underlying structures until the last user is gone. Switch to using the tty-port reference counter to...
CVE-2024-27027
In the Linux kernel, the following vulnerability has been resolved: dpll: fix dpllxarefdel for multiple registrations Currently, if there are multiple registrations of the same pin on the same dpll device, following warnings are observed: WARNING: CPU: 5 PID: 2212 at drivers/dpll/dpllcore.c:143...
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 fact that LUNRESET after tmrlist takes a reference counter on abort and waits for it to complete. Howeve...
kernel: net/sched: cls_u32 component reference counter leak if tcf_change_indev() fails
A double-free flaw was found in u32setparms in net/sched/clsu32.c in the Network Scheduler component in the Linux kernel. This flaw allows a local attacker to use a failure event to mishandle the reference counter, leading to a local privilege escalation threat...
