https://notcve.org/view.php?id=CVE-2024-50211
In the Linux kernel, the following vulnerability has been resolved: udf: refactor inode_bmap() to handle error Refactor inode_bmap() to handle error since udf_next_aext() can return error now. On situations like ftruncate, udf_extend_file() can now detect errors and bail out early without resorting to checking for particular offsets and assuming internal behavior of these functions. • https://git.kernel.org/stable/c/493447dd8336607fce426f7879e581095f6c606e https://git.kernel.org/stable/c/b22d9a5698abf04341f8fbc30141e0673863c3a6 https://git.kernel.org/stable/c/c226964ec786f3797ed389a16392ce4357697d24 •

https://notcve.org/view.php?id=CVE-2024-50210
In the Linux kernel, the following vulnerability has been resolved: posix-clock: posix-clock: Fix unbalanced locking in pc_clock_settime() If get_clock_desc() succeeds, it calls fget() for the clockid's fd, and get the clk->rwsem read lock, so the error path should release the lock to make the lock balance and fput the clockid's fd to make the refcount balance and release the fd related resource. However the below commit left the error path locked behind resulting in unbalanced locking. Check timespec64_valid_strict() before get_clock_desc() to fix it, because the "ts" is not changed after that.

In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Fix a bug while setting up Level-2 PBL pages Avoid memory corruption while setting up Level-2 PBL pages for the non MR resources when num_pages > 256K. There will be a single PDE page address (contiguous pages in the case of > PAGE_SIZE), but, current logic assumes multiple pages, leading to invalid memory access after 256K PBL entries in the PDE. • https://git.kernel.org/stable/c/0c4dcd602817502bb3dced7a834a13ef717d65a4 https://git.kernel.org/stable/c/df6fed0a2a1a5e57f033bca40dc316b18e0d0ce6 https://git.kernel.org/stable/c/de5857fa7bcc9a496a914c7e21390be873109f26 https://git.kernel.org/stable/c/ea701c1849e7250ea41a4f7493e0a5f136c1d47e https://git.kernel.org/stable/c/87cb3b0054e53e0155b630bdf8fb714ded62565f https://git.kernel.org/stable/c/daac56dd98e1ba814c878ac0acd482a37f2ab94b https://git.kernel.org/stable/c/7988bdbbb85ac85a847baf09879edcd0f70521dc •

https://notcve.org/view.php?id=CVE-2024-50207
In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Fix reader locking when changing the sub buffer order The function ring_buffer_subbuf_order_set() updates each ring_buffer_per_cpu and installs new sub buffers that match the requested page order. This operation may be invoked concurrently with readers that rely on some of the modified data, such as the head bit (RB_PAGE_HEAD), or the ring_buffer_per_cpu.pages and reader_page pointers. However, no exclusive access is acquired by ring_buffer_subbuf_order_set(). Modifying the mentioned data while a reader also operates on them can then result in incorrect memory access and various crashes. Fix the problem by taking the reader_lock when updating a specific ring_buffer_per_cpu in ring_buffer_subbuf_order_set(). • https://git.kernel.org/stable/c/8e7b58c27b3c567316a51079b375b846f9223bba https://git.kernel.org/stable/c/a569290525a05162d5dd26d9845591eaf46e5802 https://git.kernel.org/stable/c/09661f75e75cb6c1d2d8326a70c311d46729235f •
