AZL-97752 CVE-2026-80541 affecting package kernel for versions less than 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate GEMCREATE domain combinations AMDGPUGEMCREATE checked domain bits against AMDGPUGEMDOMAINMASK, but did not validate domain combinations. Userspace could combine CPU|GTT|VRAM with DOORBELL, GDS, GWS, or OA,...

UBUNTU-CVE-2026-80584

In the Linux kernel, the following vulnerability has been resolved: s390/qeth: validate user buffer length in SNMP and ARP query ioctls qethsnmpcommand and qethl3arpquery allocate a buffer sized by a user-supplied length udatalen without checking a lower bound, then set udataoffset to a fixed...

CVE-2026-80584

CVE-2026-80584 is a heap buffer overflow in the Linux kernel's s390/qeth network driver, affecting the qeth_snmp_command() and qeth_l3_arp_query() ioctls. The root cause is an unsigned integer underflow: a user-supplied udata_len smaller than the fixed non-zero udata_offset causes the bounds-chec...

CVE-2026-79619

On Linux, several OpenZFS ioctl authorization checks accept a capability held only within a user-created, unprivileged namespace as equivalent to real host privilege, allowing an unprivileged local user to perform operations that should require root. Affected operations include pool-administrativ...

CVE-2026-79619

CVE-2026-79619 affects OpenZFS on Linux, where several ioctl authorization checks incorrectly treat a capability held only within a user-created, unprivileged namespace as equivalent to real host privilege. This allows an unprivileged local user to perform root-requiring operations such as pool c...

CVE-2026-58094

The FIOSSHMLPGCNF ioctl2 operation configures the page size for a largepage shared memory object. This is intended to be used immediately after creating the object, before any memory is allocated for the object. The handler checked whether a page size had already been configured without holding t...

kernel: i2c: stub: Reject I2C block transfers with invalid length

A flaw was found in the Linux kernel's i2c-stub driver. A local user with access to the /dev/i2c- device can exploit this vulnerability by issuing an I2C System Management Bus SMBus input/output control ioctl command with a specially crafted block transfer length. This invalid length can cause th...
