In the Linux kernel, the following vulnerability has been resolved: s390/pkey: Wipe sensitive data upon failure. Also, wipe sensitive data from the stack if the copytouser function fails...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: sparc: Fixed inaccurate exception reporting in copyfromtouser for UltraSPARC III. Anthony Yznaga discovered that a bug in the ext4 code, where large amounts of data were allowed, resulted from copyfromuser returning impossibly...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: sparc: fixed inaccurate exception reporting in copyfromtouser for UltraSPARC. The referenced commit introduced exception handlers for user-space memory references in copyfromuser and copytouser. These handlers return from the...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: hwrng: core – Fix page fault deadlock on mmap-ed hwrng There is a dead-lock in the hwrng device read path. This occurs when the user reads from /dev/hwrng into memory, and at the same time, /dev/hwrng is also mapped into memory...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fix potential AB/BA lock issue with buffermutex and mmaplock The syzbot tool detected a potential deadlock between the runtime-buffermutex and the mm-mmaplock. This issue arose due to the recent fix related to racy...

CVE-2026-72441 ieee802154: fix kernel-infoleak in dgram_recvmsg()

In the Linux kernel, the following vulnerability has been resolved: ieee802154: fix kernel-infoleak in dgramrecvmsg KMSAN reported a kernel-infoleak in moveaddrtouser: BUG: KMSAN: kernel-infoleak in instrumentcopytouser include/linux/instrumented.h:131 inline BUG: KMSAN: kernel-infoleak in...

CVE-2026-68369

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: printer: fix infinite loop in printerread printerread uses the same variable for the requested copy size and the number of bytes actually copied to user space. copytouser returns the number of bytes not copied, so wh...

CVE-2026-68369

The CVE affects the Linux kernel USB gadget printer driver (printer_read) where the code used the same variable for the requested copy size and the actual copied bytes. If copy_to_user fails to copy anything, the copied length becomes zero and RX data can cause an infinite loop because len/buf/cu...

CVE-2026-64290

A flaw was found in the Linux kernel's iommufd component. When a copytouser operation fails within the iommufdfaultfopsread function, the system enters an infinite loop. This continuous retry consumes 100% of the CPU and holds a mutex, which can lead to a denial of service DoS for affected system...
