CVE-2023-28772 [MEDIUM] CWE-119 kernel: lib/seq_buf.c has a seq_buf_putmem_hex buffer overflow
kernel: lib/seq_buf.c has a seq_buf_putmem_hex buffer overflow
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.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Package: kernel (Red Hat Enterprise Linux 6) - Not affected

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
