The vulnerabilities in the net/bluetooth/eir.c and net/bluetooth/mgmt.c modules of Linux kernel allow a hacker to cause a service failure.

The vulnerability in the net/bluetooth/eir.c and net/bluetooth/mgmt.c modules of Linux kernel systems relates to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause a system failure...

The vulnerability of the aiptekirq() function in the drivers/input/tablet/aiptek.c module of the Linux kernel allows a hacker to cause a service failure.

The vulnerability of the aiptekirq function in the drivers/input/tablet/aiptek.c module of the Linux kernel is related to the lack of data validation for data received in interrupt packets from potentially compromised USB devices. Exploiting this vulnerability could allow an attacker to cause...

kernel: gfs2: Fix slab-use-after-free in qd_put

A flaw was found in the Linux kernel's GFS2 file system. During filesystem shutdown, quota data objects were freed without being properly removed from the Least Recently Used LRU list. This oversight could lead to a use-after-free vulnerability, where the system attempts to access memory that has...

kernel: Linux kernel: Denial of Service in QFQ scheduler via child qlen manipulation

A flaw was found in the Linux kernel's Quick Fair Queuing QFQ scheduler. The QFQ class deactivation logic incorrectly relies on a child qdisc's queue length qlen to determine if a class is active. A local user with CAPNETADMIN capabilities can manipulate the child qlen into an unexpected state...

kernel: Linux kernel: Use-after-free in xc5000 tuner driver due to race condition

A use-after-free flaw was identified in the Linux kernel’s media tuner xc5000 driver. In the vulnerable code path, xc5000release calls canceldelayedwork to cancel a pending delayed work item timersleep without guaranteeing that the work handler has fully completed. Under a race condition, the...

kernel: net: ip6_gre: require CAP_NET_ADMIN in the device netns for changelink

A flaw was found in the Linux kernel's ip6gre and ip6erspan tunnel drivers. The changelink functions in these drivers do not adequately verify administrative capabilities CAPNETADMIN across different network namespaces. This allows a local attacker, who has CAPNETADMIN in one network namespace bu...

kernel: nvme: add missing SRCU grace period in error path

A flaw was found in the NVMe Non-Volatile Memory Express driver of the Linux kernel. The nvmeallocns function's error handling path fails to wait for all SRCU Sleepable Read-Copy Update readers to complete before freeing a namespace structure. This oversight allows a concurrent reader to access a...

kernel: netfilter: nf_conntrack: use get_unaligned_be32() in tcp_sack()

A flaw was found in the Linux kernel's netfilter connection tracking subsystem. The TCP option processing mechanism improperly assumes memory alignment when reading packet headers. A remote attacker could exploit this vulnerability by sending crafted TCP packets with misaligned SACK options throu...

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: tunnels: load network headers after skb_cow() in iptunnel_pmtud_build_icmp[v6]()

A flaw was found in the Linux kernel's tunnels module. This vulnerability, categorized as a Use-After-Free UAF, arises from improper handling of network header pointers during certain packet processing operations. Specifically, functions responsible for building Internet Control Message Protocol...

kernel: net: ip_gre: require CAP_NET_ADMIN in the device netns for changelink

A flaw was found in the Linux kernel's IP Generic Routing Encapsulation ipgre component. This vulnerability allows a local attacker with network administration capabilities in one network namespace to modify a tunnel residing in a different network namespace where they lack privileges. This is du...

kernel: nvme/ioctl: check SUBMIT_IO with nvme_cmd_allowed()

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express input/output control ioctl handling. An unprivileged local user could exploit this vulnerability by bypassing access checks in the NVMEIOCTLSUBMITIO function. This allows them to perform unauthorized I/O operations on a...

kernel: tunnels: do not assume transport header in iptunnel_pmtud_check_icmp()

A flaw was found in the Linux kernel's tunnels module. This vulnerability occurs when the iptunnelpmtudcheckicmp function is called without the skb transport header being properly set. An attacker could exploit this condition to trigger an out-of-bound memory access, which may lead to system...

kernel: KVM: SVM: Fix page overflow in sev_dbg_crypt() for ENCRYPT path

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM module, specifically within the Secure Virtual Machine SVM component. The sevdbgcrypt function, when handling encryption, incorrectly calculates the transfer length, leading to a page overflow. This memory corruption can resu...

kernel: net/mlx5: Fix slab-out-of-bounds in mlx5_query_nic_vport_mac_list

A flaw was found in the Linux kernel's mlx5 driver. The mlx5querynicvportmaclist function, which handles querying network interface card NIC virtual port vport MAC addresses, incorrectly sizes its internal buffer. When a Virtual Function VF vport is queried with a larger configured maximum, the...

kernel: RDMA/uverbs: Validate wqe_size before using it in ib_uverbs_post_send

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the ibuverbspostsend function. A local user can exploit this vulnerability by providing an invalid work queue element size wqesize from userspace without proper validation. This can lead to an...

kernel: Linux kernel: Denial of Service in RDMA/bnxt_re driver due to race condition during QP destruction

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA bnxtre driver. A local user could exploit a race condition that occurs when a Queue Pair QP is destroyed, but completion queue CQ polling continues. This can lead to a kernel panic, resulting in a Denial of Service DoS on the...

kernel: vxlan: require CAP_NET_ADMIN in the device netns for changelink

A flaw was found in the Linux kernel's VXLAN Virtual Extensible LAN implementation. A local attacker, with CAPNETADMIN network administration capability in one network namespace, could exploit an incorrect privilege check in the rtnl changelink path. This allows the attacker to modify the...

kernel: nvme-pci: fix mempool alloc size

A flaw was addressed in the Linux kernel’s nvme-pci driver related to how the driver calculated the worst-case number of PRP Physical Region Page lists required for a given I/O request. The implementation previously rounded the allocation to one list instead of correctly converting the maximum si...

kernel: net: mana: Fix TOCTOU double-fetch of hwc_msg_id from DMA buffer

A flaw was found in the Linux kernel's mana network driver. This Time-of-Check to Time-of-Use TOCTOU vulnerability allows a hardware component to modify a message identifier hwcmsgid in Direct Memory Access DMA memory after it has been validated but before it is used. This manipulation bypasses...
