It was discovered that some AMD processors did not properly clear data in
the floating point divider unit during speculative execution. A local
attacker could use this to expose sensitive information. (CVE-2025-54505)
It was discovered that some AMD Zen 2 processors did not properly isolate
shared resources in the operation cache. A local attacker could possibly
use this issue to corrupt instructions executed at a higher privilege
level, resulting in privilege escalation. (CVE-2025-54518)

CVE-2026-23334 CWE-131 kernel: can: usb: f81604: handle short interrupt urb messages properly
kernel: can: usb: f81604: handle short interrupt urb messages properly
In the Linux kernel, the following vulnerability has been resolved:
can: usb: f81604: handle short interrupt urb messages properly
If an interrupt urb is received that is not the correct length, properly
detect it and don't attempt to treat the data as valid.
A flaw was found in the Linux kernel's `can: usb: f81604` module. This vulnerability arises when the system processes Universal Serial Bus (USB) interrupt request blocks (URBs) that are shorter than their expected length. Improper handling of these malformed messages could lead to unexpected system behavior or resource issues, potentially resulting in a Denial of Service (DoS).
