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-2026-98051

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-2026-97612

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-2026-97614

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...

UBUNTU-CVE-2026-97615

In the Linux kernel, the following vulnerability has been resolved: net: bridge: use option bits for CFM/MRP frame handlers CFM and MRP register a global brframetype whose hlistnode is linked into the per-bridge frametypelist when the first MEP/MRP instance is created. Enabling the protocol on...

UBUNTU-CVE-2026-97613

In the Linux kernel, the following vulnerability has been resolved: net: mana: Reserve extra CQ slot for the fence completion CQE The RX completion queue is sized to hold exactly one CQE per posted RX WQE. MANAFENCERQ makes hardware post an additional CQERXOBJECTFENCE after the packet CQEs. The...

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-2026-98030

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-2026-97989

In the Linux kernel, the following vulnerability has been resolved: vduse: validate virtqueue alignment vdusevalidateconfig only checks the upper bound of vqalign. Invalid values can therefore reach vringcreatevirtqueuemap. The split-ring helpers use align - 1 as a bit mask, so the alignment must...

CVE-2026-98131

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix dma mapping leak in stmmactsoxmit In stmmactsoxmit, if the DMA mapping of an skb fragment fails, the frame is dropped but the DMA mappings already created for the linear part and for the fragments mapped before t...

CVE-2026-98131 net: stmmac: fix dma mapping leak in stmmac_tso_xmit()

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix dma mapping leak in stmmactsoxmit In stmmactsoxmit, if the DMA mapping of an skb fragment fails, the frame is dropped but the DMA mappings already created for the linear part and for the fragments mapped before t...

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...

CVE-2026-98105

The Linux kernel contains a vulnerability in the oa_tc6 ethernet driver where oversubscribed traffic causing buffer overflow errors can lead to a kernel assert during skb_put. This occurs because the driver fails to identify a data chunk with the end_valid bit set before exhausting sk buffer spac...

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...

CVE-2026-98104 net/sched: cls_u32: fix duplicate handle when node ID pool is exhausted

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...

CVE-2026-98104

The Linux kernel contains a vulnerability in the net/sched: cls_u32 component where the node ID pool can become exhausted. When the pool is full, gen_new_kid() fails to report an error and instead returns a maximum value, leading u32_change() to insert a duplicate handle into the hash table. Simi...
