UBUNTU-CVE-2026-97954

In the Linux kernel, the following vulnerability has been resolved: net/rds: fix tcp stream corruption with large pages rdsmessagemappages assigns PAGESIZE bytes to every scatterlist entry, even when totallen ends in a partial page. The RDS congestion map is defined as 8192 bytes, so on systems...

UBUNTU-CVE-2026-98071

In the Linux kernel, the following vulnerability has been resolved: net/rds: clear cpflags bits individually in rdsconnpathreset rdsconnpathreset wipes the whole flag word with a plain cp-cpflags = 0 store. Every other accessor of that word uses atomic bitops, and some of them can run concurrentl...

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-2026-98068

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-2026-98030

In the Linux kernel, the following vulnerability has been resolved: net: dsa: bcmsf2: bound the CFP rule dump by the caller's buffer size bcmsf2cfprulegetall walks the whole cfp.unique bitmap into rulelocs without consulting nfc-rulecnt, which is how many entries the caller had room for...

UBUNTU-CVE-2026-97612

In the Linux kernel, the following vulnerability has been resolved: net: mpls: clear innerprotocol when the last label is popped skbmplspush records the pre-encapsulation network header once, gated on !skb-innerprotocol. skbmplspop never clears that record, so it outlives the encapsulation it...

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-2026-97981

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-2026-97982

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-2026-98016

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix use-after-free race in samplerestoreput Concurrent teardown of TC sample rules sharing the same restore context may re-read restore-count after dropping restorelock. At that point another thread may already have...

UBUNTU-CVE-2026-98051

In the Linux kernel, the following vulnerability has been resolved: net: bcmasp: fix txspbringfull checking same slot cnt times The loop initialised nextindex from intf-txspbindex on every iteration, so incrring always produced the same result and only one slot was ever tested. Move the...

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-2026-97963

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: initialize ptplock at probe time priv-ptplock is only initialized in stmmacptpregister, which runs during stmmacopen. However, the lock is also used while the interface is down and has never been opened:...
