UBUNTU-CVE-2026-98724

In the Linux kernel, the following vulnerability has been resolved: nvmet: pci-epf: reject too-short SGL segments The host controls an SGL segment's length. A nonzero length smaller than one SGL descriptor makes nrdescs zero, so nvmetpciepfgetsglsegment reads the type byte of sgls-1 outside the...

UBUNTU-CVE-2026-98725

In the Linux kernel, the following vulnerability has been resolved: nvmet-auth: fix out-of-bounds write in nvmetauthchallenge nvmetauthchallenge receives its output buffer as a void pointer. sizeofd therefore evaluates to one with GCC and undercounts the fixed challenge header by 15 bytes. A shor...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintelpcie: reject oversized TX packets in sendframe btintelpciesendframe eventually copies skb-data into a fixed BTINTELPCIEBUFFERSIZE 4096 DMA buffer via memcpy in btintelpciepreparetx, with a 4-byte PCIe type heade...

UBUNTU-CVE-2026-98732

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: fix buffer over-read in btintelhwerror The "Exception info %s" print uses skb-data + 1, but the 12-byte payload is not guaranteed to be NUL-terminated and can be read past its end. Bound the print with "%.s" a...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcicore: Serialize SCO and ISO scheduling with teardown hcilowsent selects a connection under RCU but drops the read lock before calculating its quota and returning it to the scheduler. The connection is then used...

UBUNTU-CVE-2026-98737

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: Fix inquiry cache use-after-free The sync command worker holds hdev-reqlock, but inquiry-cache updates and flushes use hdev-lock. Both hciaclcreateconnsync and hcistopdiscoverysync look up entries and read the...

UBUNTU-CVE-2026-98738

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Serialize SMP remote OOB data access buildpairingcmd looks up remote OOB data and copies its contents without holding hdev-lock, which serializes the list's writers. After SMP finds an entry, a concurrent management...
