Linux Kernel DoS, Info Disclosure Bugs Fixed
Several important security issues have been found in the Linux kernel, including a slab-out-of-bound read problem (CVE-2023-1380), a heap out-of-bounds read/write vulnerability in the traffic control (QoS) subsystem (CVE-2023-2248), and an out-of-bounds write issue in the kernel before 6.2.13 (CVE-2023-31436). The vulnerabilities have received a National Vulnerability Database (NVD) rating of “high-severity” due to their high confidentiality, integrity and availability impact.
These issues could result in denial of service (DoS) attacks, the exposure of sensitive information, unauthorized execution of management commands, and privilege escalation attacks.
We strongly recommend that all impacted users apply the kernel updates issued by their distro(s) immediately to protect against attacks leading to loss of system access and the compromise of critical systems and confidential data.
