Descriptions du CVE

net/atm/svc.c in the ATM subsystem in the Linux kernel 2.6.27.8 and earlier allows local users to cause a denial of service (kernel infinite loop) by making two calls to svc_listen for the same socket, and then reading a /proc/net/atm/*vc file, related to corruption of the vcc table.

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.
