kernel: fanotify: fix false positive on permission events

A flaw was found in the Linux kernel's fanotify subsystem. This vulnerability allows for a bypass of permission checks because the fsnotifygetmarksafe function may incorrectly return false for marks on unrelated groups. This could enable an attacker to perform unauthorized actions by circumventin...

kernel: smb: client: fix double-free in SMB2_open() replay

A flaw was found in the Linux kernel's Server Message Block SMB client. A double-free vulnerability exists in the SMB2open replay mechanism. This occurs when a response-bearing attempt returns a replayable error and frees its response buffer, and then the cleanup process attempts to free the same...

kernel: memfd: deny writeable mappings when implying SEAL_WRITE

A flaw was found in the Linux kernel's memfd component. When the SEALEXEC flag is used to create a memory file descriptor, the SEALWRITE flag is implicitly applied to prevent writing to executable memory. However, this implicit write protection is applied after checks that should deny writable...

kernel: Linux kernel: Arbitrary code execution via userfaultfd shadow stack manipulation

A flaw was found in the Linux kernel's userfaultfd mechanism. A local attacker with userfaultfd access could register on shadow stack Virtual Memory Areas VMAs. By discarding a page and injecting a page with chosen return addresses, an attacker could achieve arbitrary code execution. This...

kernel: smb: client: fix query directory replay double-free

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error, occurs when the client attempts to free the same memory buffer twice during a directory query operation. An attacker could potentially exploit this flaw to cause memory corruption,...

kernel: crypto: qat - fix VF2PF work teardown race in adf_disable_sriov()

A flaw was found in the Linux kernel's crypto QAT QuickAssist Technology module. A race condition exists during the teardown of Virtual Function to Physical Function VF2PF work in the adfdisablesriov function. This allows a concurrently scheduled or already queued worker to attempt to access memo...

kernel: Kernel: Remote out-of-bounds write in RDMA/siw

A flaw was found in the Linux kernel's Soft iWARP siw driver. A remote attacker, by sending specially crafted Read Response segments that exceed the requested length, can trigger an out-of-bounds write. This vulnerability can lead to memory corruption, potentially causing a kernel crash or...

SMB-LINUX-CVE-2025-37899

Vulnerabilidad Use-After-Free en ksmbd del Kernel de Linux CVE-2025-37899 Descripción Se ha descubierto una vulnerabilidad de tipo use-after-free en el módulo ksmbd del kernel de Linux, responsable de la implementación del protocolo SMB Server Message Block para el intercambio de archivos en red...

grill

grill grill，即 Linux 中的全局速率限制，是一个针对 CVE-2016-5696（纯 TCP 路径外攻击）的扫描器。 安装 root@kitploit: $ go get github.com/nogoegst/grill 注意事项 前往主机的路径上绝对不要使用无线链路 。持续丢包和重传会大幅降低扫描精度。 尽可能减少 NAT 层数 （降至 0），它们会引入延迟并改变数据包。 目前 grill 平均使用约 400KBit/s，最大 500KBit/s 的出站带宽（16 个并发扫描）。 内核干扰 为避免扫描期间的内核干扰，请向防火墙添加规则以丢弃出站 RST 数据包。 对于...

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: netfilter: nft_set_pipapo_avx2: don't return non-matching entry on expiry

A flaw was found in the Linux kernel's netfilter component, specifically within the nftsetpipapoavx2 AVX2 matching functions. This vulnerability occurs when a pipapo set with an 'ipv4 . port' key is reloaded. Due to incorrect masking, the system may erroneously identify non-matching elements as...

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: 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...

Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update

An update for kernel is now available for Red Hat Enterprise Linux 9.2 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: 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: selinux: fix overlayfs mmap() and mprotect() access checks

A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...

kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...
