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: 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: 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: blk-mq: pop cached request if it is usable
A flaw was found in the Linux kernel's blk-mq component. This use-after-free vulnerability occurs when a task attempts to submit a bio a data structure for I/O operations to blk-mq. If the task is interrupted and sleeps after checking for a cached request but before using it, the cached request c...
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: crypto: pcrypt - Fix handling of MAY_BACKLOG requests
A flaw was found in the Linux kernel's pcrypt component. This vulnerability involves how the system handles certain requests, specifically MAYBACKLOG requests, which can indicate a temporary busy state. If not properly managed, the system's processing of these requests could lead to resource...
kernel: ipv6: rpl: fix hdrlen overflow in ipv6_rpl_srh_decompress()
A flaw was found in the Linux kernel's IPv6 Routing Protocol for Low-Power and Lossy Networks RPL segment routing header SRH decompression function, ipv6rplsrhdecompress. An integer overflow occurs when processing a specially crafted IPv6 packet, causing the header length calculation to truncate...
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: blk-cgroup: fix UAF in __blkcg_rstat_flush()
A flaw was found in the Linux kernel's block input/output control group blk-cgroup component. This vulnerability, a Use-After-Free UAF, occurs when multiple block control groups are released at the same time. A race condition allows one group to remove another's entries while it is still in use,...
kernel: sctp: validate cached peer INIT chunk length in COOKIE_ECHO processing
A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending a specially crafted COOKIEECHO chunk to a listening SCTP server. The server's failure to properly validate the length of a cached peer INIT chunk within...
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,...
kernel: dm-verity: fix buffer overflow in FEC calculation
A flaw was found in the dm-verity component of the Linux kernel. A buffer overflow occurs during Forward Error Correction FEC calculation, allowing an attacker to write past the end of an allocated buffer. This out-of-bounds write can corrupt the syndrome buffer, potentially leading to system...
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: sctp: validate embedded INIT chunk and address list lengths in cookie
A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. Specifically, improper validation of embedded INIT chunk and address list lengths in SCTP cookies could allow a remote attacker to trigger out-of-bounds reads. This could lead to information disclosur...
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: ata: ahci: Match EM_MAX_SLOTS with SATA_PMP_MAX_PORTS
A flaw was discovered in the Linux kernel’s AHCI driver subsystem.The driver allocated an array of 8 elements ahciempriv8, but under certain SATA Port Multiplier PMP configurations, the code in satapmpinitlinks could index up to SATAPMPMAXPORTS which may exceed 8, triggering a potential...
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: Linux kernel: Denial of Service in qla2xxx SCSI driver due to improper command handling after chip reset
A flaw was found in the Linux kernel's qla2xxx SCSI driver. This vulnerability occurs when commands sent to the firmware FW are not properly cleared after a chip reset. A local attacker could exploit a race condition during direct memory access DMA unmapping, leading to a kernel panic. This can...
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...
