23 Mar 2023 — An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer overflow. A buffer overflow write flaw was identified in seq_buf_putmem_hex in lib/seq_buf.c in seq_buf in the Linux Kernel. This issue may allow a user with special debug privileges such as ftrace or root to cause an overflow in the destination buffer due to a missing sanity check. • https://github.com/Trinadh465/linux-4.1.15_CVE-2023-28772 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

23 Mar 2023 — A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an information leak. It was discovered that the Traffic-Control Index implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges.
