UBUNTU-CVE-2026-98693

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Hold a router reference for each allocated HopID tbstop drops the reference to all DP tunnels but does not deactivate them, thus nothing cancels a dprxwork still in flight which holds its own tunnel reference and the...

UBUNTU-CVE-2026-98618

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: Handle maximum standalone channels Standalone channels use one NAPI vector for each Tx and Rx queue. fbnic's allocation path excludes FBNICMAXTXQS from that layout. A 64-Tx/64-Rx configuration therefore records 128...

UBUNTU-CVE-2026-98668

In the Linux kernel, the following vulnerability has been resolved: iio: buffer: Ensure bounce buffer used for unaligned case is zeroed. iiopushtobufferswithtsunaligned leaks uninitialized heap memory to userspace if the data passed in is not a multiple of 8 bytes and the timestamp is enabled...

UBUNTU-CVE-2026-98603

In the Linux kernel, the following vulnerability has been resolved: ovpn: replace bind when clearing stale local source The UDP output fallback clears bind-local in place when the remembered source address is no longer usable. The bind is RCU-published and read locklessly by concurrent TX, so an...

UBUNTU-CVE-2026-98543

In the Linux kernel, the following vulnerability has been resolved: bpf: fs/xattr: don't assume the inode is locked in pathunlink/pathrmdir bpflsmhasdinodelocked makes the verifier rewrite bpfset|removedentryxattr to the locked variants, which assume that the caller already holds the inode's...

UBUNTU-CVE-2026-98689

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Don't access a DP tunnel after its DPRX read was canceled tbdpdprxwork checks -dprxcanceled before it takes tb-lock so it misses a tbdpdprxstop that could not cancel the already running work. It then polls the DPRX...

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-2026-98845

In the Linux kernel, the following vulnerability has been resolved: tpm: Disable TPM on null key name mismatch The null key name check exists to protect against TPM reset attacks, so a mismatch should stop the device from serving further requests. Currently it does not disable the chip when it...

UBUNTU-CVE-2026-98542

In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: Return PERRNOCPUS in remotepartitionenable on subpartitionscpus conflict When a remote partition is created underneath an existing local partition via a non-partition PRSMEMBER intermediate cgroup, updateprstate se...

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...

CVE-2026-98794

In the Linux kernel, the following vulnerability has been resolved: ipvs: filter some flags received in the backup server While the IPVS SYNC protocol is not secure by design we can still protect the backup server from messages that can wreak havoc. This commit addresses problems from received...
