CVE-2026-72070

A flaw was found in the Linux kernel's libertastf Wi-Fi driver. This vulnerability is a use-after-free, meaning the system attempts to access memory after it has been released. This occurs when the lbtffreeadapter function, responsible for freeing adapter resources, does not properly synchronize...

CVE-2026-72067

A flaw was found in the Linux kernel's CPU hotplug mechanism. When the cpuhpinvokecallback function attempts to unwind previous operations after a failure, it can incorrectly reuse a return value. This issue allows a successful rollback to mask the original error, causing a failed CPU hotplug...

CVE-2026-72066

A flaw was found in the Linux kernel, specifically within the CPU hotplug feature. This vulnerability occurs because the statesshow function, which displays CPU hotplug state information, does not correctly limit the size of its output. An attacker could exploit this by providing a large number o...

CVE-2026-72064

A flaw was found in the Linux kernel's mana network driver. When the driver allocates receive RX buffers from page pool fragments, it fails to perform an explicit synchronization for the CPU. This oversight can lead to data integrity issues or system instability on systems configured to require...

CVE-2026-72065

A flaw was found in the Linux kernel's mana network driver. This vulnerability arises from the driver's failure to validate the packet length reported by the Network Interface Card NIC within the Receive Completion Queue Entry RX CQE before further processing. A malicious NIC, or an attacker...

CVE-2026-72062

A flaw was found in the Linux kernel's gpio: mt7621 module. This vulnerability arises from non-atomic operations on shared interrupt trigger state. When mediatekgpioirqtype is called concurrently for different interrupts on the same bank, it can lead to an overwrite of configurations. This...

CVE-2026-72060

A flaw was found in the Linux kernel's Texas Instruments TI Industrial Communication Subsystem Gigabit ICSSG ethernet driver. This vulnerability occurs because the driver attempts to read hardware performance statistics even when they are unavailable. This leads to the silent corruption of networ...

CVE-2026-72061

A flaw was found in the Linux kernel. An incorrect permission check in the ipip6changelink function, which manages IPv6 over IPv4 SIT tunnels, allows a local attacker to bypass intended security restrictions. A user with administrative capabilities CAPNETADMIN in one network namespace a virtualiz...

CVE-2026-72058

A flaw was found in the Linux kernel's ixp4xxhss network driver. The ixp4xxhssprobe function incorrectly allocates two High-Level Data Link Control HDLC network devices instead of one. This programming error leads to a memory leak, as the initially allocated device is not properly unregistered an...

CVE-2026-72057

A flaw was found in the Linux kernel's networking subsystem, specifically within the actct module. This vulnerability occurs when the kernel processes fragmented network traffic, failing to correctly preserve essential packet metadata. An attacker could exploit this by sending specially crafted...

CVE-2026-72055

A flaw was found in the Linux kernel's ip6vti component, which handles IPv6 Virtual Tunnel Interfaces. A local attacker with certain network administration privileges in one isolated network environment network namespace could exploit this vulnerability. This allows them to modify the configurati...

kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

kernel: net: sched: UAF via missing handler for TC_ACT_CONSUMED in tcf_qevent_handle

A flaw was found in the Linux kernel's traffic control TC classifier application programming interface API. The tcfqeventhandle function does not properly handle a consumed socket buffer skb when it is processed by the defragmentation engine. This can lead to a Use-After-Free UAF vulnerability,...

kernel: dlm: validate length in dlm_search_rsb_tree

A flaw was found in the Linux kernel's Distributed Lock Manager dlm module. An attacker could send specially crafted network messages with an oversized length parameter to the dlmdumprsbname function. This lack of validation can lead to an out-of-bounds write in the dlmsearchrsbtree function,...

kernel: netfilter: flowtable: strictly check for maximum number of actions

A flaw was found in the Netfilter flowtable component of the Linux kernel. This vulnerability occurs because the system does not strictly check the maximum number of hardware offload actions for IPv6, allowing it to process more actions than supported. This could potentially lead to system...

CVE-2026-72053

A flaw was found in the Linux kernel's ipip networking component. A local attacker with certain network administration capabilities in one network namespace could exploit an insufficient permission check in the ipipchangelink function. This could allow them to modify the configuration of a networ...

Important: Red Hat Security Advisory: unbound security update

An update for unbound is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from t...

CVE-2026-72051

A flaw was found in the Linux kernel's IPv6 tunnel ip6tunnel handling. A local attacker, privileged in one network namespace but not another, could exploit a missing capability check in the ip6tnlchangelink function. This vulnerability allows the attacker to modify an IPv6 tunnel residing in a...

CVE-2026-72048

A flaw was found in the Linux kernel. The ieee802154: ca8210 driver fails to free allocated memory casctl when the spiasync operation encounters an error. Under sustained Serial Peripheral Interface SPI bus contention, this can lead to repeated memory leaks. This continuous resource exhaustion ma...

CVE-2026-72047

A flaw was found in the Linux kernel's ieee802154 ca8210 driver. On 64-bit systems, a pointer truncation vulnerability occurs during internal buffer operations. This issue causes only a partial pointer to be written, leading to an uninitialized upper portion when read back. Consequently, the syst...
