kernel: Bluetooth: hci_ldisc: Clear HCI_UART_PROTO_INIT on error

A flaw was found in the Linux kernel's Bluetooth Host Controller Interface HCI Universal Asynchronous Receiver/Transmitter UART driver. When the hciregisterdev function fails, a flag indicating protocol initialization is not properly cleared. This oversight allows incoming UART data to be process...

kernel: net/sched: ets: Always remove class from active list before deleting in ets_qdisc_change

In the Linux kernel, the following vulnerability has been resolved: net/sched: ets: Always remove class from active list before deleting in etsqdiscchange [email protected] says: The vulnerability is a race condition between etsqdiscdequeue and etsqdiscchange. It leads to UAF on stru...

kernel: netfilter: synproxy: refresh tcphdr after skb_ensure_writable

A flaw was found in the Linux kernel's netfilter synproxy module. When handling TCP timestamp options, a stale pointer can be used after memory reallocation. This can result in memory corruption, where data is written to a freed memory area, or lead to packets being sent with an incorrect checksu...

AZL-112643 CVE-2026-99270 affecting package kernel 6.6.161.1-1

In the Linux kernel, the following vulnerability has been resolved: tcp: Fix potential UAF in reqsktimerhandler. When TCP socket migration fails at inetehashinsert in reqsktimerhandler, we jump to the noownership: label and free the new reqsk immediately with reqskfree. Thus, we must stop the new...

kernel: ipv4: free inet_opt and ireq_opt after an RCU grace period

A flaw was found in the Linux kernel's IPv4 networking subsystem. A race condition occurs during concurrent processing of retransmitted Transmission Control Protocol TCP connection requests or socket migrations, allowing socket options to be freed while still in use. A remote attacker could explo...

In the Linux kernel, the following vulnerability has been resolved: net/sched: ets: Always remove class from active list before deleting in etsqdiscchange [email protected] says: The vulnerability is a race condition between etsqdiscdequeue and etsqdiscchange. It leads to UAF on stru...

kernel: nvme-tcp: fix host memory disclosure on R2T for a read command

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express over TCP nvme-tcp component. A malicious NVMe controller can exploit this vulnerability by sending a Ready to Transfer R2T command for a read request. The host system, failing to properly validate the request direction, will...

kernel: nvmet-tcp: check INIT_FAILED before nvmet_req_uninit in digest error path

A flaw was found in the Linux kernel's NVMe over TCP target nvmet-tcp implementation. When a data digest mismatch is detected, nvmetrequninit is called unconditionally, but if the command was already in the INITFAILED state, the matching percpureftrygetlive was never performed. The resulting...

kernel: Bluetooth: hci_sync: Set HCI_CMD_DRAIN_WORKQUEUE during device close

A flaw was found in the Bluetooth hcisync component of the Linux kernel. When the hcidevclosesync function is called during a device reset, the system may experience queuing timeouts. This occurs because the HCICMDDRAINWORKQUEUE flag is not properly set, which can lead to system instability or a...

kernel: xfrm: Duplicate SPI Handling

In the Linux kernel, the following vulnerability has been resolved: xfrm: Duplicate SPI Handling The issue originates when Strongswan initiates an XFRMMSGALLOCSPI Netlink message, which triggers the kernel function xfrmallocspi. This function is expected to ensure uniqueness of the Security...

CVE-2026-99270

The Linux kernel contains a Use-After-Free (UAF) vulnerability within the reqsk_timer_handler() function of the tcp component. The issue occurs during TCP socket migration when inet_ehash_insert() fails; the system jumps to a no_ownership label and frees the new reqsk via __reqsk_free() without f...
