CVE-2026-64402

A flaw was found in the Linux kernel's coresight ultrasoc-smb component. This vulnerability involves an out-of-bounds write in the smbsyncperfbuffer function. An attacker could potentially exploit this by causing the system to write data beyond the intended memory buffer, which may lead to system...

CVE-2026-64402

In the Linux kernel, the following vulnerability has been resolved: coresight: ultrasoc-smb: Fix OOB write in smbsyncperfbuffer When the SMB sink is used as a perf AUX sink, smbupdatebuffer calls smbsyncperfbuffer to copy hardware trace data into the perf AUX ring buffer pages.

CVE-2026-64402

CVE-2026-64402 concerns the Linux kernel coresight ultrasoc-smb path: an OOB write in smb_sync_perf_buffer() can occur when the SMB sink is used as a perf AUX sink because the initial page index is derived before applying modulo normalization to the buffer size. The issue is fixed by normalizing ...
