https://notcve.org/view.php?id=CVE-2024-39478
In the Linux kernel, the following vulnerability has been resolved: crypto: starfive - Do not free stack buffer RSA text data uses variable length buffer allocated in software stack. Calling kfree on it causes undefined behaviour in subsequent operations. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: crypto: starfive: no liberar el búfer de pila Los datos de texto RSA utilizan un búfer de longitud variable asignado en la pila de software. Llamar a kfree provoca un comportamiento indefinido en operaciones posteriores. • https://git.kernel.org/stable/c/5944de192663f272033501dcd322b008fca72006 https://git.kernel.org/stable/c/d7f01649f4eaf1878472d3d3f480ae1e50d98f6c • CWE-770: Allocation of Resources Without Limits or Throttling •

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39469 – nilfs2: fix nilfs_empty_dir() misjudgment and long loop on I/O errors
https://notcve.org/view.php?id=CVE-2024-39469
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix nilfs_empty_dir() misjudgment and long loop on I/O errors The error handling in nilfs_empty_dir() when a directory folio/page read fails is incorrect, as in the old ext2 implementation, and if the folio/page cannot be read or nilfs_check_folio() fails, it will falsely determine the directory as empty and corrupt the file system. In addition, since nilfs_empty_dir() does not immediately return on a failed folio/page read, but continues to loop, this can cause a long loop with I/O if i_size of the directory's inode is also corrupted, causing the log writer thread to wait and hang, as reported by syzbot. Fix these issues by making nilfs_empty_dir() immediately return a false value (0) if it fails to get a directory folio/page. • https://git.kernel.org/stable/c/2ba466d74ed74f073257f86e61519cb8f8f46184 https://git.kernel.org/stable/c/2ac8a2fe22bdde9eecce2a42cf5cab79333fb428 https://git.kernel.org/stable/c/405b71f1251e5ae865f53bd27c45114e6c83bee3 https://git.kernel.org/stable/c/c77ad608df6c091fe64ecb91f41ef7cb465587f1 https://git.kernel.org/stable/c/11a2edb70356a2202dcb7c9c189c8356ab4752cd https://git.kernel.org/stable/c/129dcd3e7d036218db3f59c82d82004b9539ed82 https://git.kernel.org/stable/c/d18b05eda7fa77f02114f15b02c009f28ee42346 https://git.kernel.org/stable/c/59f14875a96ef93f05b82ad3c980605f2 •
