https://notcve.org/view.php?id=CVE-2023-52915
In the Linux kernel, the following vulnerability has been resolved: media: dvb-usb-v2: af9035: Fix null-ptr-deref in af9035_i2c_master_xfer In af9035_i2c_master_xfer, msg is controlled by user. When msg[i].buf is null and msg[i].len is zero, former checks on msg[i].buf would be passed. Malicious data finally reach af9035_i2c_master_xfer. If accessing msg[i].buf[0] without sanity check, null ptr deref would happen. We add check on msg[i].len to prevent crash.

In the Linux kernel, the following vulnerability has been resolved: Input: MT - limit max slots syzbot is reporting too large allocation at input_mt_init_slots(), for num_slots is supplied from userspace using ioctl(UI_DEV_CREATE).

https://notcve.org/view.php?id=CVE-2024-45007
In the Linux kernel, the following vulnerability has been resolved: char: xillybus: Don't destroy workqueue from work item running on it Triggered by a kref decrement, destroy_workqueue() may be called from within a work item for destroying its own workqueue. This illegal situation is averted by adding a module-global workqueue for exclusive use of the offending work item. Other work items continue to be queued on per-device workqueues to ensure performance. • https://git.kernel.org/stable/c/409b495f8e3300d5fba08bc817fa8825dae48cc9 https://git.kernel.org/stable/c/5d3567caff2a1d678aa40cc74a54e1318941fad3 https://git.kernel.org/stable/c/a7ad105b12256ec7fb6d6d1a0e2e60f00b7da157 https://git.kernel.org/stable/c/aa1a19724fa2c31e97a9be48baedd4692b265157 https://git.kernel.org/stable/c/ccbde4b128ef9c73d14d0d7817d68ef795f6d131 •
