{"apiVersion":"1.0","identifier":"CVE-2026-72298","description":"In the Linux kernel, the following vulnerability has been resolved: net: qrtr: fix 32-bit integer overflow in qrtr_endpoint_post() qrtr_endpoint_post() validates an incoming packet with if (!size || len != ALIGN(size, 4) + hdrlen) goto err; where size comes from the wire. On 32-bit, size_t is 32 bits and ALIGN(size, 4) wraps to 0 for size >= 0xfffffffd, so the check passes and skb_put_data(skb, data + hdrlen, size) writes past the hdrlen-sized skb and oopses the kernel. 64-bit is unaffected. This is the 32-bit residual of ad9d24c9429e2 (-net: qrtr: fix OOB Read in qrtr_endpoint_post-), which fixed only the 64-bit case. Reject any size that cannot fit the buffer before the ALIGN.","publishedAt":"2026-08-15T06:22:02","lastModifiedAt":"2026-08-17T06:18:32","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72298","cvssScore":8.4,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.0018,"riskScore":0.85,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72298","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72298","en":"https://www.redsauce.net/en/cves/CVE-2026-72298","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72298","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72298","de":"https://www.redsauce.net/de/cves/CVE-2026-72298","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72298","el":"https://www.redsauce.net/el/cves/CVE-2026-72298"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72298"}}
