{"id":"DEBIAN-CVE-2024-26587","details":"In the Linux kernel, the following vulnerability has been resolved:  net: netdevsim: don't try to destroy PHC on VFs  PHC gets initialized in nsim_init_netdevsim(), which is only called if (nsim_dev_port_is_pf()).  Create a counterpart of nsim_init_netdevsim() and move the mock_phc_destroy() there.  This fixes a crash trying to destroy netdevsim with VFs instantiated, as caught by running the devlink.sh test:      BUG: kernel NULL pointer dereference, address: 00000000000000b8     RIP: 0010:mock_phc_destroy+0xd/0x30     Call Trace:      \u003cTASK\u003e      nsim_destroy+0x4a/0x70 [netdevsim]      __nsim_dev_port_del+0x47/0x70 [netdevsim]      nsim_dev_reload_destroy+0x105/0x120 [netdevsim]      nsim_drv_remove+0x2f/0xb0 [netdevsim]      device_release_driver_internal+0x1a1/0x210      bus_remove_device+0xd5/0x120      device_del+0x159/0x490      device_unregister+0x12/0x30      del_device_store+0x11a/0x1a0 [netdevsim]      kernfs_fop_write_iter+0x130/0x1d0      vfs_write+0x30b/0x4b0      ksys_write+0x69/0xf0      do_syscall_64+0xcc/0x1e0      entry_SYSCALL_64_after_hwframe+0x6f/0x77","modified":"2026-09-15T09:03:00.984057168Z","published":"2024-02-22T17:15:08.937Z","upstream":["CVE-2024-26587"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-26587"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.15-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-26587.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.15-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-26587.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
