https://notcve.org/view.php?id=CVE-2023-53458
01 Oct 2025 — In the Linux kernel, the following vulnerability has been resolved: media: cx23885: Fix a null-ptr-deref bug in buffer_prepare() and buffer_finish() When the driver calls cx23885_risc_buffer() to prepare the buffer, the function call dma_alloc_coherent may fail, resulting in a empty buffer risc->cpu. Later when we free the buffer or access the buffer, null ptr deref is triggered. This bug is similar to the following one: https://git.linuxtv.org/media_stage.git/commit/?id=2b064d91440b33fba5b452f2d1b31f13ae91... • https://git.kernel.org/stable/c/f0a06203f2fe63f04311467200c99c4ee1926578 •

This could be solved by checking if the filesystem is read-only before calling txBegin, and returning with appropiate error code. This update provides the initial livepatch for this kernel update.

01 Oct 2025 — In the Linux kernel, the following vulnerability has been resolved: scsi: qla4xxx: Add length check when parsing nlattrs There are three places that qla4xxx parses nlattrs: - qla4xxx_set_chap_entry() - qla4xxx_iface_set_param() - qla4xxx_sysfs_ddb_set_param() and each of them directly converts the nlattr to specific pointer of structure without length checking. This could be dangerous as those attributes are not validated and a malformed nlattr (e.g., length 0) could result in an OOB read that leaks heap di... • https://git.kernel.org/stable/c/00c31889f7513e9ffa6b2b4de8ad6d7f59a61c80 •
