UBUNTU-CVE-2023-6270

A flaw was found in the ATA over Ethernet AoE driver in the Linux kernel. The aoecmdcfgpkts function improperly updates the refcnt on struct netdevice, and a use-after-free can be triggered by racing between the free on the struct and the access through the skbtxq global queue. This could lead to...

kernel: wifi: mt76: mt7921s: fix slab-out-of-bounds access in sdio host

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921s: fix slab-out-of-bounds access in sdio host SDIO may need addtional 511 bytes to align bus operation. If the tailroom of this skb is not big enough, we would access invalid memory region. For low level...

kernel: wifi: fix potential NULL-ptr deref after clone

A flaw was found in the Linux kernel’s iwlwifi mei driver. When the driver attempts to clone a socket bufferand that operation fails, it may erroneously dereference a NULL pointer, leading to a kernel crash or denial of service. An unprivileged local user may be able to trigger this flaw by...
