26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: media: staging: media: zoran: move videodev alloc Move some code out of zr36057_init() and create new functions for handling zr->video_dev. This permit to ease code reading and fix a zr->video_dev memory leak. • https://git.kernel.org/stable/c/bd01629315ffd5b63da91d0bd529a77d30e55028 •

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: powerpc/set_memory: Avoid spinlock recursion in change_page_attr() Commit 1f9ad21c3b38 ("powerpc/mm: Implement set_memory() routines") included a spin_lock() to change_page_attr() in order to safely perform the three step operations. But then commit 9f7853d7609d ("powerpc/mm: Fix set_memory_*() against concurrent accesses") modify it to use pte_update() and do the operation safely against concurrent access. In the meantime, Maxime reported ... • https://git.kernel.org/stable/c/6def4eaf0391f24be541633a954c0e4876858b1e •

22 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: usb: cdc-acm: Check control transfer buffer size before access If the first fragment is shorter than struct usb_cdc_notification, we can't calculate an expected_size. Log an error and discard the notification instead of reading lengths from memory outside the received data, which can lead to memory corruption when the expected_size decreases between fragments, causing `expected_size - acm->nb_index` to wrap.
