5.5 CVE-2025-38612

Enriched by CISA Patch
 

In the Linux kernel, the following vulnerability has been resolved: staging: fbtft: fix potential memory leak in fbtft_framebuffer_alloc() In the error paths after fb_info structure is successfully allocated, the memory allocated in fb_deferred_io_init() for info->pagerefs is not freed. Fix that by adding the cleanup function on the error path.

CWE-401 : Missing Release of Memory after Effective Lifetime
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse. Fuzz testing (fuzzing) is a powerful technique for generating large numbers of diverse inputs - either randomly or algorithmically - and dynamically invoking the code with those inputs. Even with random inputs, it is often capable of generating unexpected results such as crashes, memory corruption, or resource consumption. Fuzzing effectively produces repeatable test cases that clearly indicate bugs, which helps developers to diagnose the issues. Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.) Use an abstraction library to abstract away risky APIs. Not a complete solution. The Boehm-Demers-Weiser Garbage Collector or valgrind can be used to detect leaks in code. Memory leak because function does not free() an element of a data structure. Memory leak when counter variable is not decremented. chain: reference count is not decremented, leading to memory leak in OS by sending ICMP packets. Kernel uses wrong function to release a data structure, preventing data from being properly tracked by other code. Memory leak via unknown manipulations as part of protocol test suite. Memory leak via a series of the same command.
