# CVE-2025-37872: linux: In the Linux kernel, the following vulnerability has been resolved: net: txgbe: fix memory leak in txgbe_probe() err... CVE-2025-37872 is fixed in 36 products on 1 platform, first by DEBIAN-CVE-2025-37872, released May 9, 2025. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2025-37872 - Priority: Routine - CVSS: 5.5 (medium) - EPSS: 0.0031 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: May 9, 2025 ## Description In the Linux kernel, the following vulnerability has been resolved: net: txgbe: fix memory leak in txgbe_probe() error path When txgbe_sw_init() is called, memory is allocated for wx->rss_key in wx_init_rss_key(). However, in txgbe_probe() function, the subsequent error paths after txgbe_sw_init() don't free the rss_key. Fix that by freeing it in error path along with wx->mac_table. Also change the label to which execution jumps when txgbe_sw_init() fails, because otherwise, it could lead to a double free for rss_key, when the mac_table allocation fails in wx_sw_init(). ## Where
