CVE-2026-45893
Description
A flaw was found in the Linux kernel's AppArmor security module. This vulnerability occurs when AppArmor attempts to create tables from user-provided data that may be unaligned in memory. A local attacker could exploit this by providing specially crafted input, leading to unaligned memory accesses. This could result in system instability or unexpected behavior.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Memory
If the untrusted pointer is used in a read operation, an attacker might be able to read sensitive portions of memory.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
If the untrusted pointer references a memory location that is not accessible to the program, or points to a location that is "malformed" or larger than expected by a read or write operation, the application may terminate unexpectedly.
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands; Modify Memory
If the untrusted pointer is used in a function call, or points to unexpected data in a write operation, then code execution may be possible.
