kernel: vxlan: do not reuse cached ip_hdr() value after skb_tunnel_check_pmtu()
A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN module. This vulnerability occurs because a cached IP header pointer is improperly reused after a Path Maximum Transmission Unit PMTU check. When the packet's head is modified during the PMTU check, the old cached IP header point...
kernel: ALSA: usx2y: bound the hwdep mmap fault offset
A flaw was found in the Advanced Linux Sound Architecture ALSA usx2y driver in the Linux kernel. A local attacker, by opening the hwdep node of an attached US-X2Y device, could exploit an unbounded memory mapping mmap fault offset. This allows read-write access to arbitrary kernel memory,...

An update for kernel is now available for Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions. 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...
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...
kernel: Bluetooth: MGMT: validate LTK enc_size on load
A flaw was found in the Linux kernel's Bluetooth management MGMT component. An attacker could exploit a vulnerability in how Long Term Keys LTK are loaded. By providing an oversized encryption size, a stack buffer overflow can occur, potentially leading to a denial of service...
kernel: scsi: target: configfs: Bound snprintf() return in tg_pt_gp_members_show()
A flaw was found in the Linux kernel's SCSI target subsystem. This vulnerability, a buffer overflow, occurs in the tgptgpmembersshow function when processing long iSCSI IQN names. An attacker could potentially exploit this by providing a specially crafted input, leading to the disclosure of...
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: procfs: fix missing RCU protection when reading real_parent in do_task_stat()
A flaw was found in the Linux kernel's procfs component. When reading /proc/pid/stat, the dotaskstat function accesses task-realparent without proper Read-Copy-Update RCU protection. This missing protection creates a race condition, which can lead to a Use-After-Free UAF vulnerability. A local...
kernel: selinux: check connect-related permissions on TCP Fast Open
A flaw was found in the Linux kernel's Security-Enhanced Linux SELinux module. When using TCP Fast Open, SELinux failed to properly check connect-related permissions. This oversight could allow a local attacker to bypass SELinux network access controls, potentially enabling unauthorized network...
kernel: crypto: af_alg - Cap AEAD AD length to 0x80000000
A flaw was found in the Linux kernel's afalg cryptography module. This vulnerability involves an arithmetic overflow when processing associated data lengths during the transmit buffer size check. A remote attacker could exploit this flaw by providing a specially crafted associated data length,...
kernel: netfilter: nfnetlink_cthelper: fix OOB read in nfnl_cthelper_dump_table()
A flaw was found in the Linux kernel's nfnetlinkcthelper component. This vulnerability, an out-of-bounds read, occurs in the nfnlcthelperdumptable function when a network connection tracking helper is removed during a dump operation, leading to a bypassed bounds check. A local attacker could...
kernel: scsi: qla2xxx: Bound rsp_info_len to avoid OOB sense-data read
A flaw was found in the Linux kernel's scsi: qla2xxx driver. A remote attacker, by sending a specially crafted Fibre Channel Protocol FCP response, could cause an integer underflow. This underflow leads to an out-of-bounds read when handling sense data, potentially disclosing sensitive memory...
kernel: mac802154: llsec: add skb_cow_data() before in-place crypto
A flaw was found in the Linux kernel's mac802154 IEEE 802.15.4 MAC security component. This vulnerability allows for data corruption and potential kernel crashes when cryptographic transformations are performed on shared network packet data without proper isolation. A remote attacker could exploi...
kernel: Bluetooth: SCO: fix race conditions in sco_sock_connect()
A flaw was found in the Linux kernel, specifically within its Bluetooth Synchronous Connection-Oriented SCO component. This vulnerability occurs due to race conditions when multiple connection attempts are made simultaneously on the same Bluetooth socket. This can lead to a use-after-free error,...
