In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Fix potential races in dat skey functions When datcondsetstoragekey finds a large page, it will conditionally set the storage key in absolute memory using largecrstetophys to get the absolute address. There is a race...

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-2026-98618

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...

In the Linux kernel, the following vulnerability has been resolved: net/rds: size a connection's path set by the transport it ends up with rdsconncreate computes npaths from the caller's transport before it decides whether a connection to one of the host's own addresses is to be handled by the...

UBUNTU-CVE-2026-98868

In the Linux kernel, the following vulnerability has been resolved: dm-pcache: reject a kset that overruns its segment cachereplay, the writeback worker and the GC worker read a kset of getksetonmediasize bytes and advance the position by it. A forged keynum makes that size exceed the segment's...

UBUNTU-CVE-2026-98821

In the Linux kernel, the following vulnerability has been resolved: block: reject polled dio with user integrity metadata IOCBHASMETADATA leaves iocb-private as a uiometa, while iocbbioiopoll expects a bio. Since 2729a60bbfb9, metadata I/O always uses blkdevdirectIO, which never publishes the bio...
