CVE-2025-71070

CVE-2025-71070 relates to the Linux kernel ublk driver. A reference-count leak on server exit could allow user copy and zero-copy on completed ublk requests due to a path that skipped decrementing the refcount in certain flows. The issue was addressed by commits that fixed the ublk_io_release pat...

CVE-2025-71070 ublk: clean up user copy references on ublk server exit

In the Linux kernel, the following vulnerability has been resolved: ublk: clean up user copy references on ublk server exit If a ublk server process releases a ublk char device file, any requests dispatched to the ublk server but not yet completed will retain a ref value of UBLKREFCOUNTINIT. Befo...

CVE-2025-68820 ext4: xattr: fix null pointer deref in ext4_raw_inode()

In the Linux kernel, the following vulnerability has been resolved: ext4: xattr: fix null pointer deref in ext4rawinode If ext4getinodeloc fails e.g. if it returns -EFSCORRUPTED, iloc.bh will remain set to NULL. Since ext4xattrinodedecrefall lacks error checking, this will lead to a null pointer...
