Уязвимость функции fastrpcmaplookup модуля drivers/misc/fastrpc.c ядра операционной системы Linux связана с неправильным освобождением памяти «утечка памяти». Эксплуатация уязвимости может позволить нарушителю, действующему удалённо, вызвать отказ в обслуживании...

CVE-2025-68252

CVE-2025-68252: In the Linux kernel misc: fastrpc component, a reference to a dma_buf obtained via dma_buf_get in fastrpc_map_lookup was not released on all return paths, causing a dma_buf memory leak. The fix adds dma_buf_put before returning (ensuring the temporary reference is released whether...

CVE-2025-68252: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: Fix dmabuf object leak in fastrpcmaplookup In fastrpcmaplookup, dmabufget is called to obtain a reference to the dmabuf for comparison purposes. However, this reference is never released when the function returns,...

CVE-2022-48874

A vulnerability was found in the Linux kernel's fastrpc.c driver. A race condition is possible between the time that the fastrpcmaplookup function unlocks a mutex and the reference count is increased by the fastrpcmapget function in the fastrpcmapfind function. This race condition could result in...
