Description

In the Linux kernel, the following vulnerability has been resolved: iio: pressure: bmp280: fix out-of-bounds access in sampling frequency lookup The sampling frequency tables store each frequency as an integer part and a fractional part in micro units. num_sampling_freq_avail is initialized to the number of flattened integer elements because read_avail() returns the table as a flat array. bmp280_write_sampling_frequency(), however, indexes the same table as a two-dimensional array and uses num_sampling_freq_avail as the number of rows. Convert the flattened element count back to the number of rows before iterating over the table.

CVE-2026-98620

A critical kernel bug in the MediaTek Ethernet driver (mtk_eth_soc) causes a BUG_ON when register_netdev() fails, potentially leading to a kernel panic. The flaw occurs during probe failure handling, leaving net_devices in a registered state before they are freed. This can disrupt network services and overall system stability.

CVE-2026-98627

CVE-2026-98627 is a critical flaw in the Linux kernel’s BPF subsystem that allows out‑of‑bounds packet pointer accesses due to incorrect displacement handling. The vulnerability can be triggered by malicious BPF programs, potentially enabling memory corruption or privilege escalation. It was fixed by a kernel commit that corrected the pointer offset logic.

CVE-2026-98628

In the Linux kernel, the following vulnerability has been resolved: bpf: Make post-verification instruction rewrites killable After do_check() returns, the verifier runs several instruction rewrite passes. Some of them patch or remove one instruction at a time. Each operation moves the remaining instruction and auxiliary-data arrays and adjusts all branch offsets, making the overall work quadratic in the program length. A privileged loader can submit 131072 unconditional jumps by zero followed by a valid return. Verification finishes quickly, but bpf_opt_remove_nops() then spends a long time removing each jump separately. Since this post-verification work neither checks for signals nor reschedules, a pending SIGKILL cannot terminate the task until the rewrite finishes. Make bpf_patch_insn_data() and verifier_remove_insns() common cancellation and rescheduling points. These helpers run from BPF_PROG_LOAD process context, and bpf_patch_insn_data() can already sleep while reallocating auxiliary data. Report interrupted constant blinding as -EINTR and propagate it through both JIT paths, including kernels that permit interpreter fallback. Other blinding failures retain the existing fallback behavior. This does not reduce the quadratic cost of the rewrite passes, but it makes the work preemptible and allows a killed loader to be torn down promptly.

CVE-2026-98634

In the Linux kernel, the following vulnerability has been resolved: scsi: sd_zbc: Reject disks with too many zones sd_zbc_read_zones() computes the number of zones with 64-bit arithmetic and stores the result in the unsigned int nr_zones field of struct zoned_disk_info, silently truncating counts that exceed 32 bits. The truncated count is later used to size per-zone resources, while the device may still report more zones than fit. Moreover, sd_zbc_report_zones() counts the reported zones with a signed int zone_idx, which overflows past INT_MAX. Reject devices reporting more than INT_MAX zones at scan time; such a device is not realistic for any medium that exists today, and accepting it produces inconsistent zone bookkeeping.
