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: scsi: target: iscsi: Fix CRC overread and double-free in iscsit_handle_text_cmd()

A flaw was found in the Linux kernel's iSCSI Internet Small Computer System Interface target subsystem. This vulnerability involves a buffer overread and a double-free error when processing iSCSI Text commands. A remote attacker could exploit these issues by sending specially crafted network...

kernel: sctp: don't free the ASCONF's own transport in DEL-IP processing

A flaw was found in the Stream Control Transmission Protocol SCTP implementation within the Linux kernel. A remote attacker could send a specially crafted sequence of ASCONF Add IP Address Configuration chunks, including DEL-IP Delete IP Address parameters, to trigger a use-after-free condition...

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: smc: Fix use-after-free in tcp_write_timer_handler()

In the Linux kernel, the following vulnerability has been resolved: smc: Fix use-after-free in tcpwritetimerhandler. With Eric's ref tracker, syzbot finally found a repro for use-after-free in tcpwritetimerhandler by kernel TCP sockets. 0 If SMC creates a kernel socket in smccreate, the kernel...

kernel: tipc: fix double-free in tipc_buf_append()

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. This vulnerability, a double-free, occurs when the tipcbufappend function incorrectly handles memory after a socket buffer skb reallocation. An attacker could potentially exploit this to cause system...

kernel: scsi: target: iscsi: Bound iscsi_encode_text_output() appends to rsp_buf

A flaw was found in the Linux kernel's iSCSI Internet Small Computer System Interface target functionality. This vulnerability, a heap overrun, occurs because the iscsiencodetextoutput function does not properly check buffer capacity when processing login requests. A remote attacker could exploit...

CVE-2026-87082

Net::IDN::Punycode versions before 2.590 for Perl hang, crash or return a wrong label via unvalidated malformed UTF-8 in encodepunycode. Neither backend checks that its input is well-formed UTF-8, so a string with the UTF-8 flag set over malformed bytes, as the :utf8 PerlIO layer produces from an...

CVE-2026-87081

Net::IDN::UTS46 versions before 2.590 for Perl allow CPU exhaustion via quadratic punycode encoding of an overlong label before the length check in toascii. toascii punycode encodes each label and only then applies the 63-byte DNS limit. encodepunycode in both backends follows the sample...

CVE-2026-87080

Net::IDN::Punycode::PP versions before 2.590 for Perl decode a truncated label to a name containing a character it never encoded in decodepunycode. The pure-Perl decoder reads one digit at a time with four-argument substr and tests the result with defined to detect the end of the input. substr on...

CVE-2026-87079

Net::IDN::Punycode versions before 2.590 for Perl allow CPU exhaustion via quadratic insertion cost when decoding a long label in decodepunycode. The XS backend inserts each decoded code point into a UTF-8 buffer and finds the insertion point by scanning that buffer from the start, one character ...

CVE-2026-87078

Net::IDN::Punycode versions from 2.302 before 2.590 for Perl leak the output buffer on every rejected label in decodepunycode. The XS backend allocates the scalar it returns before it validates the input, sizing the buffer at twice the input length. The scalar is released only on the success path...
