Linux kernel 安全漏洞
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a possible concurrent execution of the tcpskexitbatch function of the tcp component...
kernel: tcp: Fix shift-out-of-bounds in dctcp_update_alpha().
A security vulnerability has been identified in the TCP networking implementation of the Linux kernel. Specifically, the dctcpupdatealpha function is susceptible to a shift-out-of-bounds condition. This flaw could potentially be exploited to cause unexpected behavior or a denial-of-service...
kernel: tcp: Use refcount_inc_not_zero() in tcp_twsk_unique().
A use-after-free flaw was found in the Linux kernel’s TCP protocol in how a local user triggers a complex race condition during connection to the socket. This flaw allows a local user to crash or potentially escalate their privileges on the system...

edk2: Predictable TCP Initial Sequence Numbers
A security flaw has been identified in EDK2, the open-source reference implementation of the UEFI specification. This vulnerability enables an unauthorized attacker to potentially disclose sensitive information...
kernel: tcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV sockets
In the Linux kernel, the following vulnerability has been resolved: tcp: defer shutdownSENDSHUTDOWN for TCPSYNRECV sockets TCPSYNRECV state is really special, it is only used by cross-syn connections, mostly used by fuzzers. In the following crash 1, syzbot managed to trigger a divide by zero in...
kernel: tcp: make sure init the accept_queue's spinlocks once
In the Linux kernel, the following vulnerability has been resolved: tcp: make sure init the acceptqueue's spinlocks once When I run syz's reproduction C program locally, it causes the following issue: pvqspinlock: lock 0xffff9d181cd5c660 has corrupted value 0x0! WARNING: CPU: 19 PID: 21160 at...

UBUNTU-CVE-2024-41079
In the Linux kernel, the following vulnerability has been resolved: nvmet: always initialize cqe.result The spec doesn't mandate that the first two double words aka results for the command queue entry need to be set to 0 when they are not used not specified. Though, the target implemention return...
The vulnerability of the BIND DNS server, related to uncontrolled resource consumption, allows a hacker to cause a service failure.
The vulnerability of the BIND DNS server is related to uncontrolled resource consumption. Exploiting this vulnerability allows a malicious actor to cause service failures by sending a large number of DNS requests via the TCP protocol...

ISC BIND 安全漏洞
ISC BIND is an ISC open source suite of open source software that implements the DNS protocol. A security vulnerability exists in ISC BIND 9, which stems from the fact that a large number of DNS messages on TCP may destabilize the server...
UBUNTU-CVE-2024-0760
A malicious client can send many DNS messages over TCP, potentially causing the server to become unstable while the attack is in progress. The server may recover after the attack ceases. Use of ACLs will not mitigate the attack. This issue affects BIND 9 versions 9.18.1 through 9.18.27, 9.19.0...

UBUNTU-CVE-2022-48819
In the Linux kernel, the following vulnerability has been resolved: tcp: take care of mixed splice/sendmsgMSGZEROCOPY case syzbot found that mixing sendpage and sendmsgMSGZEROCOPY calls over the same TCP socket would again trigger the infamous warning in inetsockdestruct WARNONskforwardallocgetsk...
DEBIAN-CVE-2024-41007
In the Linux kernel, the following vulnerability has been resolved: tcp: avoid too many retransmit packets If a TCP socket is using TCPUSERTIMEOUT, and the other peer retracted its window to zero, tcpretransmittimer can retransmit a packet every two jiffies 2 ms for HZ=1000, for about 4 minutes...
