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...
nginx: Fix of CVE-2026-1642
CVE-2026-1642: detect premature plain text response from SSL backend...
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...
CVE-2026-74766
Net::IDN::Punycode versions from 2.301 before 2.590 for Perl allow a heap use-after-free via a decoded code point that reallocates the output buffer in decodepunycode. The XS backend inserts each decoded code point into the string buffer of the scalar it returns. decodepunycode computes the...
CVE-2026-74765
Net::IDN::Punycode versions before 2.590 for Perl allow an out-of-bounds read via integer overflow of the delta accumulator in encodepunycode. The XS backend keeps the punycode delta, and the digit index derived from it, in a signed int. The accumulation delta += m-n h+1 has no overflow check, so...
CVE-2016-15059
Net::IDN::Punycode versions before 2.301 for Perl allow a heap buffer overflow via unchecked writes past the output buffer in encodepunycode. The XS backend builds the encoded label in the string buffer of the scalar it returns, sized from the input length. The loop that emits the digits of each...
SoupWebsocketExtensionDeflate: libsoup: libsoup: WebSocket permessage-deflate Unbounded Decompression Remote Denial of Service
A flaw was found in libsoup's WebSocket implementation when using the permessage-deflate extension. The extension's decompression loop inflate processes data in chunks without enforcing an upper boundary limit on the output buffer size. While libsoup limits the incoming compressed frame size via...
libsoup: SoupWebsocketConnection: libsoup: WebSocket remote denial of service via oversized control frame protocol violation
A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames e.g., PING, PONG, CLOSE contain a payload of 125 bytes or less. A remote, unauthenticated attacker...
redis: Redis: Remote Code Execution via specially crafted RESTORE payload
A flaw was found in Redis. An authenticated attacker, in an unusual configuration where they can execute the RESTORE command, could exploit a double free vulnerability. This occurs when a specially crafted RESTORE payload references the same NACK pending entry by multiple consumers, and both...
redis: Redis: Arbitrary code execution via TLS pending-data list use-after-free
A flaw was found in Redis. This vulnerability, a use-after-free, exists within the tlsProcessPendingData function, which manages the Transport Layer Security TLS pending-data list when Redis is configured with TLS support. A remote, unauthenticated attacker could exploit this to execute...
gstreamer-plugins-base: GStreamer: Arbitrary code execution via OGG file parsing buffer overflow
A flaw was found in GStreamer. This vulnerability, a stack-based buffer overflow, occurs during the parsing of OGG files due to improper validation of user-supplied data length. A remote attacker could exploit this by tricking a user into visiting a malicious page or opening a malicious file,...
