Linux Distros Unpatched Vulnerability : CVE-2026-87823

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - zstd-jni before 1.5.7-14 performs 32-bit signed bounds checks on three direct-ByteBuffer frame-size native methods, allowing out-of-bounds memory reads via...

PT-2026-89053

zstd-jni before 1.5.7-14 performs 32-bit signed bounds checks on three direct-ByteBuffer frame-size native methods, allowing out-of-bounds memory reads via negative or overflowing offsets. Attackers can supply negative offset values near Integer.MIN VALUE to read unmapped memory, causing JVM...

SUSE CVE-2026-68462

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject negative const offsets for buffer pointers The verifier rejects variable offsets for PTRTOTPBUFFER and PTRTOBUF accesses, but it currently accepts a constant negative offset produced by pointer arithmetic. Commit...

CVE-2026-68462

Summary of CVE-2026-68462 (Linux kernel, BPF): The issue arises in the verifier’s handling of buffer-pointer access (PTR_TO_TP_BUFFER and PTR_TO_BUF) where a constant negative offset could slip through after a pointer offset split (reg->var_off vs reg->off). Specifically, an access with reg...

CVE-2026-11743

The SF32LB MPI QSPI NOR flash driver drivers/flash/flashsf32lbmpiqspinor.c validated the flash offset and length on its read and write paths with the test offset + size data-size. Because offset is a signed offt while size is unsigned, a negative offset is converted to a large unsigned value and...
