In the Linux kernel, the following vulnerability has been resolved: net/smc: fix UAF on lgr list traversal in smcrporterr smcrporterr traverses smclgrlist.list without holding smclgrlist.lock, allowing a concurrent smclgrterminatesched to free an lgr while it is still being dereferenced. Hold...

UBUNTU-CVE-2026-98595

In the Linux kernel, the following vulnerability has been resolved: udp: remove a disconnected socket from the 4-tuple hash table A UDP socket bound to a specific address and port keeps its entry in the 4-tuple hash table after it is disconnected: sk binds to 127.0.0.1:21001 sk connects to...

UBUNTU-CVE-2026-98570

In the Linux kernel, the following vulnerability has been resolved: net: ipv6: keep room for the mac header in dstdevoverhead The seg6, ioam6 and rpl lwtunnels size their skbcowhead request as the length they are about to push plus dstdevoverhead, then push the new headers and rebuild the mac...

UBUNTU-CVE-2026-98584

In the Linux kernel, the following vulnerability has been resolved: net/sched: fix potential stack infoleak in emtextdump emtextdump allocates struct tcfemtext on the stack without zeroing it. strscpy writes the algorithm name and a NUL terminator into conf.algo, leaving the remaining bytes...

UBUNTU-CVE-2026-98613

In the Linux kernel, the following vulnerability has been resolved: bpf: Bound ownership depth through local kptrs and graph roots Program-allocated objects can own other local objects through referenced kptrs. bpfobjfreefields follows those pointers through bpfobjdropimpl synchronously, before t...

UBUNTU-CVE-2026-98594

In the Linux kernel, the following vulnerability has been resolved: tg3: clean up PHYLIB resources on probe failure tg3getinvariants can register an MDIO bus and connect a PHY for USEPHYLIB devices. If tg3initone later fails, its common error path releases the mappings and netdev without undoing...

UBUNTU-CVE-2026-98561

In the Linux kernel, the following vulnerability has been resolved: nfp: hold IPsec RX state under the XArray lock nfpnetipsecrx drops the XArray lock before taking a reference to the xfrmstate it found. The delete path can erase the entry and drop the last state reference in that interval. RX ca...

UBUNTU-CVE-2026-98751

In the Linux kernel, the following vulnerability has been resolved: tty: abort break signalling on hangup The break ioctls can race with hangup and end up calling into a tty driver for a device that is already gone or powered down. Drivers must handle this race, but TCSBRK and TCSBRKP should stil...

UBUNTU-CVE-2026-98731

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintelpcie: fix plen overflow in btintelpcierecvframe plen is u16 and computed as HDRSIZE + dlen. For ACL/ISO frames dlen is a 16-bit field, so a value = 0xFFFC wraps the sum, bypassing the "skb-len plen" check and...
