UBUNTU-CVE-2026-98027

In the Linux kernel, the following vulnerability has been resolved: net: dsa: mv88e6xxx: bound the policy rule dump by the caller's buffer size mv88e6xxxgetrxnfc uses rxnfc-rulecnt as the write index while dumping the policy IDR, clobbering the input value before it has been looked at. That input...

UBUNTU-CVE-2026-98104

In the Linux kernel, the following vulnerability has been resolved: net/sched: clsu32: fix duplicate handle when node ID pool is exhausted gennewkid falls back to returning max htid | 0xFFF when both idrallocu32 ranges are full, instead of reporting an error. u32change trusts that value and inser...

UBUNTU-CVE-2026-98017

In the Linux kernel, the following vulnerability has been resolved: net/sched: defer qdisc freeing after failed creation An RTMNEWQDISC request can make clsact bind a populated shared ingress block during -init, publishing an embedded miniQdisc to lockless readers. If the same request has an...

UBUNTU-CVE-2026-98010

In the Linux kernel, the following vulnerability has been resolved: net/sched: drr: clamp quantum in change class drrchangeclass rejects explicit quantum==0 but falls back to pschedmtu with no floor. With a crafted size table qdiscpktlen reaches 2 GiB, so quantum=1 or a zero pschedmtu on a...

UBUNTU-CVE-2026-97618

In the Linux kernel, the following vulnerability has been resolved: iouring/net: don't overconsume buffers when using MSGTRUNC When a recv/recvmsg is issued with MSGTRUNC and the incoming packet is larger than the provided buffer, the net layer returns the full length of the packet rather than th...

UBUNTU-CVE-2026-98009

In the Linux kernel, the following vulnerability has been resolved: net/sched: ets: clamp quantum in parse and fallback paths etsqdiscchange falls back to pschedmtu with no floor for bands without an explicit quantum. With a crafted size table qdiscpktlen reaches 2 GiB, so a zero pschedmtu on a...

UBUNTU-CVE-2026-98068

In the Linux kernel, the following vulnerability has been resolved: net/rds: don't let rdsconnshutdown consume a concurrent drop rdsconnshutdown finishes by moving the path from RDSCONNDISCONNECTING to RDSCONNDOWN, and also accepts RDSCONNERROR as the starting state of that final transition, so...

UBUNTU-CVE-2026-97982

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Fix budget accounting The gmacrx function returns the remaining NAPI budget, but its caller treats the return value as the number of packets received. An idle poll therefore reports a full budget and remai...

UBUNTU-CVE-2026-98072

In the Linux kernel, the following vulnerability has been resolved: net/rds: use wqhassleeper in releaseinxmit releaseinxmit clears RDSINXMIT with clearbitunlock and then checks waitqueueactive to decide whether anyone needs waking. clearbitunlock is only a release operation: it orders the critic...

UBUNTU-CVE-2026-97981

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Count dropped frames as NAPI work The RX loop only consumes budget when it successfully delivers a frame. Error paths keep consuming descriptors without reducing the budget, so a stream of bad frames can...

UBUNTU-CVE-2026-98070

In the Linux kernel, the following vulnerability has been resolved: net/rds: acquire RDSINXMIT in rdstcpresetcallbacks rdstcpresetcallbacks quiesces the transmit path by setting the path state to RDSCONNRESETTING and then waiting for RDSINXMIT to be sampled clear before swapping the underlying...

UBUNTU-CVE-2026-98069

In the Linux kernel, the following vulnerability has been resolved: net/rds: acquire the fastpath locks in rdsconnshutdown rdsconnshutdown quiesces the transmit and receive-refill paths by waiting for RDSINXMIT and RDSRECVREFILL to be sampled clear, and then runs the transport shutdown and...

UBUNTU-CVE-2026-98105

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: oatc6: Improve the error recovery When oversubscribed traffic causes lot of buffer overflow errors, probably due to loss of data chunks, driver fails to find a data chunk with endvalid bit set, before it runs out o...

UBUNTU-CVE-2026-98011

In the Linux kernel, the following vulnerability has been resolved: net/sched: hhf: clamp quantum in change and init paths hhfchange accepts any quantum from userspace, including 1. With a crafted size table qdiscpktlen reaches 2 GiB, so quantum=1 makes the deficit-refill loop spin 2^31 times und...

In the Linux kernel, the following vulnerability has been resolved: net: dsa: tagbrcm: legacy FCS: request needed tailroom The legacy FCS tagger calculates the CRC over skb-len bytes starting at skb-data. When a nonlinear skb reaches the tagger, this reads past the linear head into unrelated slab...
