DEBIAN-CVE-2023-6238

A buffer overflow vulnerability was found in the NVM Express NVMe driver in the Linux kernel. Only privileged user could specify a small meta buffer and let the device perform larger Direct Memory Access DMA into the same buffer, overwriting unrelated kernel memory, causing random kernel crashes...

CVE-2023-6238

CVE-2023-6238 affects the Linux kernel NVMe driver. A buffer overflow allows a privileged user to provide a small meta buffer and trigger a larger DMA into that same buffer, overwriting unrelated kernel memory and causing random kernel crashes/memory corruption. The vulnerability is locally explo...

USN-6497-1: Linux kernel (OEM) vulnerabilities

Maxim Levitsky discovered that the KVM nested virtualization SVM implementation for AMD processors in the Linux kernel did not properly handle x2AVIC MSRs. An attacker in a guest VM could use this to cause a denial of service host kernel crash. CVE-2023-5090 Alon Zahavi discovered that the...

kernel: use after free in nvmet_tcp_free_crypto in NVMe

A use-after-free vulnerability was found in drivers/nvme/target/tcp.c in nvmettcpfreecrypto due to a logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead t...
