USN-6572-1 linux-azure vulnerabilities

Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service system crash. CVE-2023-31085 Bien Pham discovered that the netfiler subsystem in the Linux...

CVE-2022-4172

An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table ERST device of QEMU in the readerstrecord and writeerstrecord functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could...

DEBIAN-CVE-2022-2085

A NULL pointer dereference vulnerability was found in Ghostscript, which occurs when it tries to render a large number of bits in memory. When allocating a buffer device, it relies on an initdeviceprocs defined for the device that uses it as a prototype that depends upon the number of bits per...

A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMA_REG_DSRHIGH" write from the guest and may result in a crash of QEMU or cause undefined behavior due to the access of an uninitialized pointer. The highest threat from this vulnerability is to system availability.

DEBIAN-CVE-2021-3607

An integer overflow was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMAREGDSRHIGH" write from the guest due to improper input validation. This flaw allows a privileged guest user to make QEMU allocate a lar...

The vulnerability of the Azure Sphere operating system’s MTD driver allows a hacker to execute arbitrary code.

The vulnerability of the Azure Sphere operating system’s driver relates to errors in code generation management. Exploiting this vulnerability could allow an attacker to execute arbitrary code...

kernel: mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism

The mm subsystem in the Linux kernel through 4.10.10 does not properly enforce the CONFIGSTRICTDEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte and bypass slab-allocation access restrictions via an application that opens the...
