CVE-2026-93141

CVE-2026-93141 is a double-free vulnerability in the Linux kernel's Renesas R8A66597 USB gadget driver (r8a66597). When usb_add_gadget_udc() fails during device probe, the ep0_req request structure is freed in the err_add_udc error path and then freed a second time in clean_up2, leading to a doub...

CVE-2026-93140

CVE-2026-93140 affects the Linux kernel's UDF filesystem . When an I/O error occurs while writing the Logical Volume Integrity Descriptor (LVID) buffer, the block layer clears the BH_Uptodate flag, even though the in-memory data remains valid. Subsequent calls to udf_open_lvid() or udf_sync_fs() ...
