Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 6.1.128/6.6.77/6.12.13/6.13.2. This issue affects the function handle_policy_update of the component safesetid. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: safesetid: check size of policy writes syzbot attempts to write a buffer with a large size to a sysfs entry with writes handled by handle_policy_update(), triggering a warning in kmalloc. Check the size specified for write buffers before allocating. [PM: subject tweak]
