kernel: Kernel: Privilege escalation via uninitialized data in vmci transport packet
A flaw was found in the Linux kernel's vsock/vmci component. A local attacker with low privileges could exploit a vulnerability where the vmcitransportpacket structure is not properly cleared during initialization. This can lead to the use of uninitialized data, potentially allowing for informati...
kernel: rxrpc: Fix potential UAF after skb_unshare() failure
A flaw was found in the Linux kernel's rxrpc subsystem. This vulnerability arises when the system attempts to unshare a packet buffer, and the operation fails due to an allocation issue. This failure can lead to a Use-After-Free UAF condition, where the system attempts to access memory that has...
kernel: net: ipv6: fix NOREF dst use in seg6 and rpl lwtunnels
A flaw was found in the Linux kernel's IPv6 networking implementation, specifically within the seg6 and rpl lwtunnels. A race condition can occur when handling destination cache entries, where a NOREF no reference destination object is used after it has been freed. This use-after-free vulnerabili...
kernel: USB: serial: io_ti: fix heap overflow in get_manuf_info()
A flaw was found in the Linux kernel's ioti USB serial driver. A malicious USB device, when plugged into a host running this driver, can exploit a heap overflow vulnerability in the getmanufinfo function. This occurs because the driver does not properly validate the size of data read from the...
kernel: RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()
A flaw was found in the Linux kernel's RDMA/mana component. A local user could trigger a kernel corruption by providing specific configurations through the user Application Programming Interface uAPI that cause an internal error. This issue arises when Work Queues WQs are specified to share the...
kernel: RDMA/mana: Validate rx_hash_key_len
A flaw was found in the Linux kernel's RDMA/mana component. A local user could exploit this vulnerability by providing an invalid rxhashkeylen value through a user-space API uAPI structure. This invalid value is then used in a memcpy operation without proper bounds checking, allowing the user to...
kernel: ipv6: fix possible UAF in icmpv6_rcv()
A flaw was found in the Linux kernel's IPv6 Internet Protocol version 6 implementation. This vulnerability, a Use-After-Free UAF error, occurs due to incorrect caching of network packet addresses before a memory operation. An attacker could potentially exploit this flaw to cause memory corruption...
kernel: ice: fix double-free of tx_buf skb
A flaw was found in the Linux kernel's ice network driver. An error in the driver's handling of network packet transmission, specifically when icetso or icetxcsum functions fail, can lead to a double-free of a network buffer skb. This occurs because a transmit buffer txbuf may still point to an...
kernel: crypto: qat - validate RSA CRT component lengths
A flaw was found in the Linux kernel's QAT QuickAssist Technology crypto module. This vulnerability occurs in the RSA key parser when handling CRT Chinese Remainder Theorem components. An underflow can happen during a memory copy operation if an RSA CRT component is larger than its allocated...
kernel: Bluetooth: hci_event: fix potential UAF in SSP passkey handlers
A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a Use-After-Free UAF, exists within the Secure Simple Pairing SSP passkey handlers. It occurs when hciconn lookup and field access are performed without proper locking, allowing a connection to be freed concurrently...
kernel: i2c: stub: Reject I2C block transfers with invalid length
A flaw was found in the Linux kernel's i2c-stub driver. A local user with access to the /dev/i2c- device can exploit this vulnerability by issuing an I2C System Management Bus SMBus input/output control ioctl command with a specially crafted block transfer length. This invalid length can cause th...

kernel: packet: use consistent hard_header_len in non-ring send paths
An out-of-bounds write problem was observed in packetsendmsgspkt in net/packet/afpacket.c in the Linux Kernel. In this flaw, AFPACKET hardheaderlen race may allow local privilege escalation...
kernel: Bluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp
A flaw was found in the Linux kernel's Bluetooth Logical Link Control and Adaptation Protocol L2CAP implementation. A remote Bluetooth Low Energy BLE device can exploit this by sending a specially crafted L2CAP ECRED reconfiguration response. This can lead to the corruption of the channel list,...
kernel: can:bcm: arbitrary kernel code execution leading to escalate privileges
A flaw was found in the Linux kernel in net/can/bcm.c in can: bcm, where an unprivileged local user can exploit this vulnerability to execute arbitrary code within the kernel, which leads to a local privilege escalation LPE. This allows the attacker to gain root privileges and take full control o...
