Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.5.0-rc2+ Description The vulnerability is related to the lt8912b driver in the Linux kernel, which causes a crash on bridge detach due to a NULL pointer dereference. The driver's bridge detach function calls dr...

The vulnerability in the `drivers/media/usb/ttusb-dec/ttusb_dec.c` component of the Linux kernel allows a attacker to perform a “denial-of-service” attack.

The vulnerability of the drivers/media/usb/ttusb-dec/ttusbdec.c component in the Linux operating system is related to a memory leak due to the absence of the dvbfrontenddetach function being called. Exploiting this vulnerability can allow an attacker to perform a type of “denial-of-service” attac...

The vulnerability of the Linux operating system’s PCMCIA kernel driver allows a hacker to cause a service failure or exert other adverse effects.

The vulnerability of the Linux operating system’s PCMCIA kernel driver is related to the race condition between the functions cmmopen and cm4000detach in the drivers/char/pcmcia/cm4040cs.c file. This race condition causes the previously freed memory to be used again. An attacker can exploit this...

OESA-2023-1511 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: A flaw was found in the Linux kernel’s IP framework for transforming packets XFRM subsystem. This issue may allow a malicious user with CAPNETADMIN privileges to directly dereference a NULL pointer in xfrmupdateaeparams, leading ...

kernel: use-after-free vulnerability in the perf_group_detach function of the Linux Kernel Performance Events

The Linux kernel's Performance Events subsystem has a use-after-free flaw that occurs when a user triggers the perfgroupdetach and removeonexec functions simultaneously. This flaw allows a local user to crash or potentially escalate their privileges on the system...

Linux kernel resource management error vulnerability

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 post-release reuse issue discovered in the cxgb4 driver, which crashes the system and results in a denial ...

A flaw was found in the MCTP protocol in the Linux kernel. The function mctp_unregister() reclaims the device's relevant resource when a netcard detaches. However a running routine may be unaware of this and cause the use-after-free of the mdev->addrs object potentially leading to a denial of service.
