Description
This security bulletin contains information about 1 vulnerability.
1) Memory leak (CVE-ID: CVE-2026-72048)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local attacker to cause a denial of service.
The vulnerability exists due to a memory leak in ca8210_spi_transfer() in the ca8210 IEEE 802.15.4 driver when submitting asynchronous SPI transfers. A local attacker can trigger spi_async() submission failures to cause a denial of service.
Repeated retry attempts under sustained SPI bus contention can leak a new allocation on each occurrence.
Remediation
Install update from vendor's website.
