PT-2026-71039

Net::CIDR::Set versions before 0.23 for Perl allow memory exhaustion and malformed set ranges via unbounded IPv6 prefix lengths. The encode method accepts any prefix length matching 0|1-90-9 and passes it to width2bits, which builds the mask as '1' x $width + 8, one character per bit. The inc...

CVE-2026-68184

A flaw was found in the Linux kernel's CD-ROM cdrom driver. When handling the CDROMVOLCTRL command, the mmcioctlcdromvolume function can perform an incorrect calculation of buffer length after a pointer adjustment. This leads to a stack out-of-bounds read, where 8 bytes of data beyond the intende...

AZL-95529 CVE-2026-72712 affecting package nmap for versions less than 7.95-5

Nmap versions up to and including 7.99 contains a denial of service vulnerability that allows remote attackers to crash the application by sending a crafted packet containing a zero-length TCP option. The malformed packet forces the Packet:parseoptions function in nselib/packet.lua to allocate...

CVE-2026-68339

A flaw was found in the Linux kernel's Bluetooth subsystem btusb driver. An attacker could craft a two-byte vendor event that, due to improper validation of the Realtek vendor event length in the btusbrecveventrealtek function, could lead to the system attempting to read a non-existent third byte...

netty: io.netty/netty-codec-http: Netty: HTTP Request Smuggling due to improper handling of conflicting HTTP/1.0 headers

A flaw was found in Netty's HttpObjectDecoder. A remote attacker can exploit this by sending a specially crafted HTTP/1.0 request that includes both Transfer-Encoding: chunked and Content-Length headers. While Netty correctly strips the conflicting Content-Length header for HTTP/1.1 messages, thi...
