Notable security-relevant fixes include a use-after-free in usbdev_release(), an out-of-bounds write in ALSA's snd_usbmidi_novation_output(), a slab out-of-bounds read in the USB serial "option" driver's interrupt URB callback, and multiple xfrm/TCP-AO use-after-free and key-leak fixes affecting network security state handling. The crypto subsystem saw several corrections, including removal of unsafe/deprecated qce algorithms, a CCM AAD buffer underallocation fix, and safer key buffer clearing via kfree_sensitive(). Additional important work touched SELinux policy parsing hardening, ext4 WRITE_ZEROES correctness and journaling safety, KVM SEV/VMSA handling, and RDMA rxe responder QP fixes, reflecting a stability- and security-focused maintenance release.
