CVE-2025-37923

CVSS v3.1

7.8

High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.15.0-rc1-syzkaller-00301-g3bde70a2c827
Description A bug has been reported in the Linux kernel where the trace seq to buffer() function attempts to copy more data than PAGE SIZE to a buffer, resulting in an out-of-bounds write. This issue was identified by syzbot and has been resolved. The tracing splice read pipe() function is also affected.
Recommendations For Linux kernel versions prior to 6.15.0-rc1-syzkaller-00301-g3bde70a2c827, update to a newer version that includes the fix for the out-of-bounds write in trace seq to buffer(). As a temporary workaround, consider restricting access to the tracing splice read pipe() function until a patch is available.
