USN-6533-1: Linux kernel (OEM) vulnerabilities

Tom Dohrmann discovered that the Secure Encrypted Virtualization SEV implementation for AMD processors in the Linux kernel contained a race condition when accessing MMIO registers. A local attacker in a SEV guest VM could possibly use this to cause a denial of service system crash or possibly...

CBL Mariner 2.0 Security Update: kernel (CVE-2023-46813)

The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-46813 advisory. - An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access t...

Important: kernel

Issue Overview: A race condition between two functions, lmLogClose and txEnd, in the Linux kernel's JFS filesystem can lead to a use-after-free vulnerability and crash. CVE-2023-3397 An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO...

Important: kernel

Issue Overview: An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kern...

Amazon Linux 2023 : bpftool, kernel, kernel-devel (ALAS2023-2023-430)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-430 advisory.

SUSE SLES15 / openSUSE 15 Security Update : kernel (SUSE-SU-2023:4414-1)

The remote SUSE Linux SLES15 / SLESSAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4414-1 advisory. - Incorrect verifier pruning in BPF in Linux Kernel =5.4 leads to unsafe code paths being incorrectly marked as safe,...

OESA-2023-1798 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds and crash in readdescriptors in drivers/usb/core/sysfs.c.CVE-2023-37453 An issue was discovered in the Linux kernel before...

An issue was discovered in the Linux kernel before 6.5.9 exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege escalation). This depends on a race condition through which userspace can replace an instruction before the #VC handler reads it.
