CVE-2026-53195

In the Linux kernel USB serial driver io_ti, CVE-2026-53195 describes a heap-overflow in build_i2c_fw_hdr(). The function allocates a fixed buffer ((16*1024 - 512) + sizeof(struct ti_i2c_firmware_rec)) and then copies img_header->Length bytes without validating that Length fits into the remain...

openCryptoki: openCryptoki: Information disclosure and Denial of Service via malformed BER-encoded cryptographic objects

A flaw was found in openCryptoki, a PKCS11 Cryptographic Token Interface Standard library. The BER/DER Basic Encoding Rules/Distinguished Encoding Rules decoding functions in the shared common library do not properly validate attacker-controlled length fields against actual buffer boundaries. Thi...

CVE-2026-52719

GStreamer: out-of-bounds read in the VA JPEG decoder of gst-plugins-bad (CVE-2026-52719). The JPEG parser reads a segment length without validating against available data, enabling a remote attacker to craft a JPEG that, when opened by a user, may cause parsing to read beyond the input buffer, po...

gimp: GIMP: Remote Code Execution via PSP file parsing

A flaw was found in GIMP. A remote attacker could exploit this vulnerability by enticing a user to open a specially crafted PSP PaintShop Pro file. This flaw is caused by a heap-based buffer overflow, where the application does not properly validate the length of user-supplied data. Successful...
