CVE-2026-31512 Bluetooth: L2CAP: Validate PDU length before reading SDU length in l2cap_ecred_data_rcv()

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Validate PDU length before reading SDU length in l2capecreddatarcv l2capecreddatarcv reads the SDU length field from skb-data using getunalignedle16 without first verifying that skb contains at least...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from l2capecreddatarcv not verifying the PDU length before reading the SDU length, potentially leading...

In the Linux kernel, the following vulnerability has been resolved: media: dvb-net: fix OOB access in ULE extension header tables The ulemandatoryexthandlers and uleoptionalexthandlers tables in handleoneuleextension are declared with 255 elements valid indices 0-254, but the index htype is deriv...

CVE-2026-31405

CVE-2026-31405 : Linux kernel media/dvb-net vulnerability — OOB read in ULE extension header tables due to 255-element lookup arrays; bounds check added for htype to ensure out-of-range SNDU is discarded. This resolves a kernel-wide issue and is reflected in OSV advisories (e.g., Root: Debian 11/...

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Fix MSDU buffer types handling in RX error path Currently, packets received on the REO exception ring from unassociated peers are of MSDU buffer type, while the driver expects link descriptor type packets. These...

CVE-2025-68729 wifi: ath12k: Fix MSDU buffer types handling in RX error path

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Fix MSDU buffer types handling in RX error path Currently, packets received on the REO exception ring from unassociated peers are of MSDU buffer type, while the driver expects link descriptor type packets. These...

CVE-2025-68729

The CVE-2025-68729 entry documents a Linux kernel issue in ath12k where MSDU buffer type packets received on the REO exception ring from unassociated peers were mis-parsed as link descriptor packets. The underlying cause was not freeing the skb, risking kernel crashes and buffer leaks. The provid...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that originates from a post-release reuse when Bluetooth L2CAP reorganizes the SDU, which could lead to memory corruption...

kernel: wifi: cfg80211: check A-MSDU format more carefully

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: check A-MSDU format more carefully If it looks like there's another subframe in the A-MSDU but the header isn't fully there, we can end up reading data out of bounds, only to discard later. Make this a bit more...
