wake-and-break

Wake and Break A PSP Platform Security Processor exploit for AMD navi31 cards RX 7900 series. Likely adaptable to other adjacent product families as well. It turns off the PSP's firmware signature check, so the card will load unsigned IP firmware SMU, SDMA, MEC, IMU, RLC that it would otherwise...

kernel: tcp: fix TIME_WAIT socket reference leak on PSP policy failure

A flaw was found in the Linux kernel's TCP implementation. A reference leak in TIMEWAIT sockets can occur upon a PSP Policy Security Policy failure in both IPv4 and IPv6 receive paths. This vulnerability can lead to a memory leak of tcptwbucket structures, potentially resulting in a Denial of...

Trinity

Trinity Trinity is the third public jailbreak for the PS Vita™ , which supports the latest firmwares 3.69 and 3.70. The exploit chain consists of three stages: the MIPS Kernel Exploit, the PSP Emulator Escape and the ARM Kernel Exploit. Write-up A technical explanation of the Trinity exploit chai...

Astra Linux – vulnerability in linux-6.18

In the Linux kernel, the following vulnerability has been resolved: net: psp: avoid conflicts with skb-decrypted and skvalidatexmitskb PSP conflicts with TLS ULP in its usage of both skb-decrypted and sk-skvalidatexmitskb. Make PSP mutually exclusive with TLS ULP, the only other user of either of...

CVE-2026-78189 WebDyne versions from 3.007 before 3.022 for Perl execute .psp files outside the document root via path traversal in the PSGI API route fallback

WebDyne versions from 3.007 before 3.022 for Perl execute .psp files outside the document root via path traversal in the PSGI API route fallback. When a request matches no file, the PSGI handler retries it as an API route through apifilename. That keeps .. segments in the request path and only...

PT-2026-134513

Name of the Vulnerable Software and Affected Versions WebDyne versions 2.031 through 3.021 Description WebDyne incorrectly identifies files as Perl pages if the string .psp appears anywhere in the filename. This occurs because the regular expression WEBDYNE PSP EXT RE used to determine if a file...

CVE-2026-98274

A flaw was found in the Linux kernel's networking subsystem. A local user could trigger a Denial of Service DoS or system instability by configuring a network socket to use both PSP encryption and a TCP Upper Layer Protocol ULP, such as TLS. Because these features conflict in how they track...

CVE-2026-99116

In the Linux kernel, the following vulnerability has been resolved: net: psp: do not inherit the Rx association on clone sk-pspassoc sits past skdontcopyend, so sockcopy copies it into every socket accepted from a listener without taking a reference, while inetsockdestruct puts for every inet...

CVE-2026-99116

A use-after-free vulnerability exists in the Linux kernel networking subsystem within the Packet Security Protocol (PSP) implementation. The flaw occurs because sk->psp_assoc is copied into sockets accepted from a listener during a sock_copy() operation without properly incrementing its refere...
