Design/Logic Flaw

Found Linux Kernel flaw in the i740 driver. The Userspace program could pass any values to the driver through ioctl interface. The driver doesn't check the value of 'pixclock', so it may cause a divide by zero error...

UBUNTU-CVE-2020-27784

A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printerioctl printerioctl tries to access of a printerdev instance. However, use-after-free arises because it had been freed by gprinterfree...

Ubuntu 18.04 LTS : Linux kernel vulnerability (USN-5591-3)

The remote Ubuntu 18.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5591-3 advisory. It was discovered that the virtual terminal driver in the Linux kernel did not properly handle VGA console font changes, leading to an out-of-bounds write. A loca...

CVE-2022-3061

Astra Linux advisories confirm a Linux kernel fix related to the pixclock divide-by-zero issue in i740/i740fb families, aligning with CVE-2022-3061. The fix involves validating pixclock before use (e.g., zero check in charger-like var handling such as savagefb_check_var / i740fb equivalent) and n...

Linux kernel 资源管理错误漏洞

Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A resource management error vulnerability exists in the Linux kernel, which arises from accessing a freed instance of printerioctl printerioctl attempts to access a printerdev instance, resulting in reus...

DEBIAN-CVE-2022-2153

A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a...

CVE-2022-1247

An issue found in linux-kernel that leads to a race condition in roseconnect. The rose driver uses roseneigh-use to represent how many objects are using the roseneigh. When a user wants to delete a roseroute via roseioctl, the rose driver calls rosedelnode and removes neighbours only if their...

Null pointer dereference

A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service...

CVE-2022-1263

CVE-2022-1263 is a Linux kernel KVM NULL pointer dereference bug that triggers when releasing a vCPU with dirty ring support enabled. An unprivileged local attacker on the host can issue specific ioctl calls to cause a kernel oops and DoS. Public advisories (e.g., Amazon Linux 2 ALAS2KERNEL-5.15-...
