In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: fix NULL dereference in setcoalesce before first open The Rx ring priv and index are only set in bcmgenetinitrxring, which runs at open. Setting the Rx coalescing parameters on an interface that was never opened,...

UBUNTU-CVE-2026-98833

In the Linux kernel, the following vulnerability has been resolved: mtd: core: call getdevice with the master MTD getmtddevice calls the master's getdevice callback with mtd, which may be a partition. putmtddevice passes the master. This breaks gluebi partitions because gluebigetdevice uses...

UBUNTU-CVE-2026-98834

In the Linux kernel, the following vulnerability has been resolved: mtd: core: avoid double-free of OTP NVMEM device If factory OTP setup fails after the user OTP NVMEM device has been registered, mtdotpnvmemadd unregisters the user device but leaves mtd-otpusernvmem set. On an error, the caller...

UBUNTU-CVE-2026-98846

In the Linux kernel, the following vulnerability has been resolved: sctp: check RCVSHUTDOWN after the sendmsg connect wait sctpwaitforconnect drops the socket lock while it sleeps. An out-of-the-blue ABORT can then be processed from the socket backlog and unlink the association. If a concurrent...

UBUNTU-CVE-2026-98847

In the Linux kernel, the following vulnerability has been resolved: rtc: spear: initialize IRQ state before requesting alarm IRQ devmrequestirq enables the interrupt before it returns, so the handler may run while probe is still initializing the device. Initialize the MMIO address and spinlock...

UBUNTU-CVE-2026-98848

In the Linux kernel, the following vulnerability has been resolved: rtc: ac100: Assign .num before accessing .hws Commit f316cdff8d67 "clk: Annotate struct clkhwonecelldata with countedby" annotated the hws member of 'struct clkhwonecelldata' with countedby, which informs the bounds sanitizer...

UBUNTU-CVE-2026-98853

In the Linux kernel, the following vulnerability has been resolved: net: gso: limit recursive IP-in-IP segmentation IP-in-IP GSO can re-enter inetgsosegment or ipv6gsosegment for each nested IP header. encaplevel tracks header bytes, not callback depth, so a deep chain can exhaust the kernel stac...

UBUNTU-CVE-2026-98495

In the Linux kernel, the following vulnerability has been resolved: net: arp: terminate device name before lookup The ARP ioctl copies a user-provided struct arpreq into a stack object. Its arpdev field may contain IFNAMSIZ bytes without a NUL terminator. Such input is passed to devgetbynamercu o...

UBUNTU-CVE-2026-98454

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix create context out-of-bounds reads smb2parsecontexts validates the complete create-context area but does not limit each record to its Next field before dispatching it. A malformed chain can therefore expose bytes...

UBUNTU-CVE-2026-98457

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: validate frame length before control and FCS access l2capdatarcv unpacks either a two-byte or four-byte control field without first ensuring that it is present. A short ERTM or streaming-mode frame can therefore...
