UBUNTU-CVE-2026-64291

In the Linux kernel, the following vulnerability has been resolved: iommufd: Set veventqdepth upper bound iommufdveventqalloc accepts any !0 veventqdepth from userspace, with an upper bound at U32MAX. This leaves a vulnerability where userspace can allocate excessively large queues to exhaust...

CVE-2026-64496 iio: event: Fix event FIFO reset race

In the Linux kernel, the following vulnerability has been resolved: iio: event: Fix event FIFO reset race iioeventgetfd creates the event file descriptor with anoninodegetfd, which allocates a new fd, creates the anonymous file and installs it in the process fd table before returning to the calle...

CVE-2026-64496

The CVE-2026-64496 issue affects the Linux kernel IIO event (iio: event) where a race between kfifo_to_user and kfifo_reset_out could lead to an out-of-bounds read and leakage of kernel memory to userspace. Root cause: iio_event_getfd() uses anon_inode_getfd() to allocate and install a new FD, th...

CVE-2026-64485 ALSA: compress: Fix task creation error unwind

In the Linux kernel, the following vulnerability has been resolved: ALSA: compress: Fix task creation error unwind sndcomprtasknew allocates the driver task before validating the returned DMA buffers and reserving file descriptors. When either of those later steps fails, the core frees its task...

CVE-2026-64375

In CVE-2026-64375, the Linux kernel fix addresses a race in ptrace access checks. Previously proc_pid_get_link() and proc_pid_readlink() looked up the task from the pid twice (before and after the check). The patch passes the task to the ->proc_get_link() handler and adds call_proc_get_link() ...
