CVE-2026-74545

In the Linux kernel, the following vulnerability has been resolved: rtase: fix double free of multi-frag skb on DMA map failure In rtasestartxmit, when the head buffer DMA mapping fails after rtasexmitfrags has mapped all fragments, the error path clears the fragment descriptors with...

CVE-2026-74545

CVE-2026-74545 is a Linux kernel issue where rtase_start_xmit() can double-free an skb on DMA map failure after fragments are mapped. The fix changes control flow to return immediately after clearing fragments when the skb owns frags; the no-frag path still frees the head skb once. Public advisor...

CVE-2026-68135 net: hip04: fix RX buffer leak on build_skb failure

In the Linux kernel, the following vulnerability has been resolved: net: hip04: fix RX buffer leak on buildskb failure When buildskb fails in hip04rxpoll, the driver jumps to the refill path without releasing the current RX buffer and its DMA mapping. Installing a replacement buffer then overwrit...

CVE-2026-31658 net: altera-tse: fix skb leak on DMA mapping error in tse_start_xmit()

In the Linux kernel, the following vulnerability has been resolved: net: altera-tse: fix skb leak on DMA mapping error in tsestartxmit When dmamapsingle fails in tsestartxmit, the function returns NETDEVTXOK without freeing the skb. Since NETDEVTXOK tells the stack the packet was consumed, the sk...

CVE-2026-31658

CVE-2026-31658 affects the Linux kernel net: altera-tse driver. The root cause is a memory leak: when dma_map_single() fails in tse_start_xmit(), the code returns NETDEV_TX_OK without freeing the skb, causing the skb to be leaked on every DMA mapping failure. The provided patches add dev_kfree_sk...

CVE-2025-37873 eth: bnxt: fix missing ring index trim on error path

In the Linux kernel, the following vulnerability has been resolved: eth: bnxt: fix missing ring index trim on error path Commit under Fixes converted txprod to be free running but missed masking it on the Tx error path. This crashes on error conditions, for example when DMA mapping fails...

CVE-2025-37873

The CVE-2025-37873 entry concerns the Linux kernel Ethernet driver for Broadcom/BNXT (eth: bnxt). The issue arises in the Tx path after a conversion to a free-running tx_prod, where masking on the Tx error path was missed, causing a crash on error conditions such as DMA mapping failures. The root...

UBUNTU-CVE-2024-50001

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix error path in multi-packet WQE transmit Remove the erroneous unmap in case no DMA mapping was established The multi-packet WQE transmit code attempts to obtain a DMA mapping for the skb. This could fail, e.g. under...
