kernel: tipc: clear sock->sk on the failed-insert path in tipc_sk_create()

A flaw was found in the Linux kernel's TIPC Transparent Inter-Process Communication protocol. A local attacker could exploit this vulnerability by repeatedly creating and failing to insert new sockets, causing the tipcskcreate function to leave a dangling pointer to a freed socket object. This...

kernel: sctp: fix auth_hmacs array size in struct sctp_cookie

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. An incorrect array size calculation for the authhmacs field within the sctpcookie structure could lead to a buffer overflow. During the initialization of an SCTP association, if four HMAC identifiers...

kernel: sctp: diag: reject stale associations in dump_one path

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP diagnostics. When performing a socket diagnostic sockdiag lookup, the system may attempt to access memory related to an SCTP association that has already been freed. This can lead to an out-of-bounds read from...

kernel: security/keys: fix missed RCU read section on lookup

A flaw was found in the Linux kernel's keyring code. The assocarrayfind function, used for looking up keys, was called without holding the necessary Read-Copy-Update RCU read lock. This oversight allows for a memory corruption vulnerability, particularly affecting persistent key handling, as the...

kernel: netfilter: nf_log: validate MAC header was set before dumping it

A flaw was found in the Linux kernel's netfilter logging component. This vulnerability occurs because the system does not properly check if a network packet's Media Access Control MAC header is valid before attempting to log it. A local attacker could send a specially crafted network packet,...

kernel: netfilter: nf_conntrack_sip: don't use simple_strtoul

A flaw was found in the Linux kernel's netfilter SIP Session Initiation Protocol connection tracking module. This vulnerability, caused by unsafe port parsing, allows a remote attacker to send specially crafted malformed packets. Such packets could lead to excessive resource consumption,...

kernel: net: pull headers in qdisc_pkt_len_segs_init()

A flaw was found in the Linux kernel's handling of Generic Segmentation Offload GSO packet headers. This vulnerability occurs when the qdiscpktlensegsinit function does not properly pull headers into the expected memory location, which can lead to incorrect processing by network drivers. A remote...

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: 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...

Exploit for Use After Free in Linux Linux_Kernel

RMV Exploit — чистая сборка CVE-2026-43499 для iQOO Neo 11 PD...

kernel: flow_dissector: do not dissect PPPoE PFC frames

A flaw was found in the Linux kernel's flow dissector. This vulnerability allows a remote attacker to cause a Denial of Service DoS by sending a specially crafted Point-to-Point Protocol over Ethernet PPPoE Protocol Field Compression PFC frame to an affected system. The incorrect processing of...

kernel: net: guard timestamp cmsgs to real error queue skbs

A flaw was found in the Linux kernel's networking component. This vulnerability allows a remote attacker to potentially access sensitive information or cause system instability. By sending specially crafted network packets, an attacker can exploit an issue in how the kernel handles timestamping f...

kernel: KVM: nSVM: Always use vmcb01 in VMLOAD/VMSAVE emulation

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM nSVM module. When a nested virtual machine L2 guest executes VMSAVE/VMLOAD instructions, and these are not intercepted by the first-level hypervisor L1, KVM incorrectly uses vmcb02 instead of vmcb01 for managing guest state...

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: Revert "net/smc: Introduce TCP ULP support"

A flaw was found in the Linux kernel's TCP User-Level Protocol ULP support for SMC. This vulnerability arises when an active TCP socket is converted into an SMC socket, as the implementation attempts to modify core Virtual File System VFS structures in-place. This action violates fundamental VFS...

kernel: netfilter: conntrack: remove sprintf usage

A flaw was found in the Linux kernel's netfilter conntrack module. This vulnerability arises from the use of sprintf and insufficient buffer sizing in the manglecontentlen function, which can lead to a stack-out-of-bounds write. An attacker could potentially exploit this memory corruption issue t...

kernel: ipv6: prevent possible UaF in addrconf_permanent_addr()

A flaw was found in the Linux kernel's IPv6 networking subsystem. Specifically, a Use-after-Free UaF vulnerability exists within the addrconfpermanentaddr function. This issue arises when the system attempts to access an IPv6 address after it has been freed, which could allow an attacker to cause...

kernel: tcp: call sk_data_ready() after listener migration

A flaw was found in the Linux kernel's TCP networking subsystem. When an established network connection is migrated between listener sockets within the same SOREUSEPORT group, applications waiting for new connections may not be properly notified. This can cause poll, epollwait, and blocking accep...

kernel: smb: client: fix double-free in SMB2_close() replay

A flaw was found in the Linux kernel's Server Message Block SMB client. A vulnerability exists in the SMB2close replay mechanism where a response buffer can be freed twice. This double-free condition can lead to memory corruption, potentially resulting in a denial of service or the execution of...

kernel: nvmet-rdma: handle inline data with a nonzero offset

A flaw was found in the nvmet-rdma component of the Linux kernel. This vulnerability arises from incorrect handling of inline data with a non-zero offset, which can lead to an integer underflow. An attacker could exploit this to cause the system to read beyond its allocated memory, potentially...
