Detailsinfo

A vulnerability was found in Linux Kernel up to 6.6.94/6.12.34/6.15.3 and classified as critical. Affected by this issue is some unknown functionality. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: media: imx-jpeg: Cleanup after an allocation error When allocation failures are not cleaned up by the driver, further allocation errors will be false-positives, which will cause buffers to remain uninitialized and cause NULL pointer dereferences. Ensure proper cleanup of failed allocations to prevent these issues.
