In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: fix negative ttbufflen batadvorignode::ttbufflen was declared as s16, but the field is never intended to hold a negative value. When a value greater than 32767 is assigned, it wraps to a negative signed integer. I...

CVE-2026-64088

CVE-2026-64088 relates to the Linux kernel’s batman-adv code, where batadv_orig_node::tt_buff_len was defined as a signed 16-bit int (s16) but not intended to hold negatives. When values exceed 32767, they wrap to negative values, and in batadv_send_other_tt_response the field is widened to s32, ...

CVE-2026-64089 batman-adv: tt: fix negative last_changeset_len

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: fix negative lastchangesetlen batadvpivtt::lastchangesetlen len was declared as s16, but the field is never intended to hold a negative value. When a value greater than 32767 is assigned, it wraps to a negative...

CVE-2026-64089

CVE-2026-64089 affects the Linux kernel Batman-Adv (batman-adv) TT code. The root cause is that last_changeset_len was declared as s16, which can wrap when values exceed 32767, producing a negative value that then propagates into a widened s32. This leads batadv_tt_prepare_tvlv_local_data() to al...

CVE-2026-53312

In the Linux kernel, the following vulnerability has been resolved: iommu/riscv: Remove overflows on the invalidation path Since RISC-V supports a sign extended page table it should support a gather-end of ULONGMAX, but if this happens it will infinite loop because of the overflow. Also avoid...

CVE-2026-53312

In CVE-2026-53312, a Linux kernel iommu/riscv vulnerability is resolved: an integer overflow in the invalidation path could cause an infinite loop when handling sign-extended page tables (ULONG_MAX) during a gather/end computation. The fix moves the +1 away from the potentially overflowed compari...
