firefox: thunderbird: Same-origin policy bypass in the Networking: Cookies component

A flaw was found in Firefox and Thunderbird. The Mozilla Foundation's Security Advisory describes the following issue: Same-origin policy bypass in the Networking: Cookies component...

Important: Red Hat Security Advisory: firefox security update

An update for firefox is now available for Red Hat Enterprise Linux 9.6 Extended Update Support. 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...

kernel: nvmet-auth: validate reply message payload bounds against transfer length

A flaw was found in the Linux kernel's nvmet-auth component. A remote attacker, by sending a specially crafted NVMe-oF NVMe over Fabrics authentication reply message, can cause an out-of-bounds read in the kernel's memory. This vulnerability, exploitable pre-authentication, can lead to the...

kernel: net: add pskb_may_pull() to skb_gro_receive_list()

A flaw was found in the Linux kernel's network Generic Receive Offload GRO handling. An attacker sending specially crafted network packets could trigger a bug in the skbgroreceivelist function. This occurs when the system attempts to process network data that is not in the expected linear memory...

kernel: smb: client: fix double-free in SMB2_close() replay

A flaw was found in the Linux kernel's Server Message Block SMB client. A vulnerability exists in the SMB2close replay mechanism where a response buffer can be freed twice. This double-free condition can lead to memory corruption, potentially resulting in a denial of service or the execution of...

kernel: ipv6: sit: reload inner IPv6 header after GSO offloads

A flaw was found in the Linux kernel's Simple Internet Transition SIT tunnel driver for IPv6. When processing network traffic with Generic Segmentation Offload GSO enabled, the driver may use a stale pointer to the inner IPv6 header after the socket buffer skb head has been reallocated. This can...

kernel: ipv6: anycast: insert aca into global hash under idev->lock

A flaw was found in the Linux kernel, specifically within its management of IPv6 anycast addresses. A timing issue, known as a race condition, can occur when these addresses are added and removed from a system's internal list. This can lead to the system attempting to access memory that has alrea...

kernel: ipv6: mcast: Fix use-after-free when processing MLD queries

A flaw was found in the Linux kernel's IPv6 multicast mcast component. When processing Multicast Listener Discovery MLD queries, a pointer to the multicast group address is not correctly reloaded after certain packet manipulations. This can lead to a use-after-free vulnerability, potentially...

kernel: ipv4: free net->ipv4.sysctl_local_reserved_ports after unregister_net_sysctl_table()

A flaw was found in the Linux kernel's IPv4 networking component. The ipv4sysctlexitnet function prematurely frees the net-ipv4.sysctllocalreservedports memory. This can lead to a use-after-free vulnerability, where other threads might attempt to access deallocated memory. Such an issue can resul...

kernel: inet: RAW sockets using IPPROTO_RAW MUST drop incoming ICMP

A flaw was found in the Linux kernel's handling of RAW sockets using IPPROTORAW. A remote attacker could send a specially crafted ICMP Internet Control Message Protocol packet. This malicious packet could set the protocol field to 255, causing it to be processed by a RAW socket configured for...

kernel: can: bcm: add locking for bcm_op runtime updates

A flaw was found in the Linux kernel's Controller Area Network CAN broadcast manager BCM. Improper locking during runtime updates of internal counters in the bcmcantx function allows a local attacker to trigger a slab-out-of-bounds read access. This vulnerability can lead to information disclosur...

kernel: net: guard timestamp cmsgs to real error queue skbs

A flaw was found in the Linux kernel's networking component. This vulnerability allows a remote attacker to potentially access sensitive information or cause system instability. By sending specially crafted network packets, an attacker can exploit an issue in how the kernel handles timestamping f...

kernel: ppp: require CAP_NET_ADMIN in target netns for unattached ioctls

A flaw was found in the Linux kernel's Point-to-Point Protocol PPP subsystem. A local unprivileged user can exploit this vulnerability by creating a new user namespace and bypassing authorization checks for unattached administrative input/output controls ioctls. This allows the user to perform...

kernel: tcp: call sk_data_ready() after listener migration

A flaw was found in the Linux kernel's TCP networking subsystem. When an established network connection is migrated between listener sockets within the same SOREUSEPORT group, applications waiting for new connections may not be properly notified. This can cause poll, epollwait, and blocking accep...

kernel: KVM: arm64: Bound used_lrs when flushing the pKVM hyp vCPU

A flaw was found in the Kernel-based Virtual Machine KVM component of the Linux kernel on ARM64 systems. A highly privileged local attacker could exploit a vulnerability where the system fails to properly restrict memory access during a specific virtual machine operation. This could allow the...
