CVE-2026-43256
Description
A flaw was found in the Linux kernel's media subsystem, specifically within the Qualcomm Camera Subsystem (CAMSS) Video Front End (VFE) driver. An out-of-bounds memory access can occur in the vfe_isr_reg_update() function when processing interrupt service routines. This vulnerability arises because a loop iterates beyond the allocated array bounds, potentially allowing a local attacker to cause a denial of service (DoS) or information disclosure.
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
