| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2025-02-26 | CVE-2021-47655 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: venus: vdec: fixed possible memory leak issue The venus_helper_alloc_dpb_bufs() implementation allows an early return on an error path when checking the id from ida_alloc_min() which would not release the earlier buffer allocation. Move the direct kfree() from the error checking of dma_alloc_attrs() to the common fail path to ensure that allocations are released on all error paths in this function. Addresses-Coverity: 1494120 ("Resource leak") | 5.5 |
| 2025-02-26 | CVE-2021-47660 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix some memory leaks in an error handling path of 'log_replay()' All error handling paths lead to 'out' where many resources are freed. Do it as well here instead of a direct return, otherwise 'log', 'ra' and 'log->one_page_buf' (at least) will leak. | 5.5 |
| 2025-02-26 | CVE-2021-4453 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: fix a potential gpu_metrics_table memory leak Memory is allocated for gpu_metrics_table in renoir_init_smc_tables(), but not freed in int smu_v12_0_fini_smc_tables(). | 5.5 |
