6.18.49 (longterm, Branch 6.18)
83 Commits, davon ca. 67 Fixes
Linux 6.18.49 (longterm) delivers a broad round of stability and hardening fixes across USB, ALSA, crypto, networking, KVM/SEV, io_uring, HID, and filesystem subsystems, with heavy emphasis on the xfrm/netfilter/TCP-AO stack and SELinux policy parsing hardening. Notable security fixes include an OOB write in ALSA's snd_usbmidi_novation_output(), a use-after-free in usb_device handling during usbdev_release(), a CCM AAD buffer underallocation and authentication-truncation key leak in crypto (qce/xfrm), and multiple SELinux fixes enforcing stricter permission-value validation against class permission counts (with one prior fix reverted due to regressions). KVM SEV received several fixes around VMSA tracking and guest-memory handling, while xfrm/espintcp and TCP-AO saw numerous use-after-free and lock-inversion corrections. Additional fixes address RDMA rxe out-of-bounds and UAF issues, veth OOB queue access, io_uring futex/eventfd handling, and various driver-level UAF/OOB bugs in USB, HID, and fuse subsystems.
